Pet Supplements FAQ

Daily care essentials: ensure ample water intake, increase urination opportunities, control weight, and reduce high-magnesium/high-phosphorus treats.

For supplementation, consider urinary-support products with herbal ingredients like Plantain herb and Knotgrass (e.g., PACKAR Urinary Care Tablets, with 12 herbal extracts).

Emergency reminder: difficulty urinating, blood in urine, or frequent trips to the litter box with little output are emergency signals—seek veterinary care immediately; do not rely on supplements to delay.

Check four dimensions:

• Entity information—is the brand and distributor a verifiable registered entity, with a filing number stated;
• Production standards—does it state compliance with GMP or similar;
• Test reports—is there third-party authoritative testing, with the institution name and report number findable;
• Ingredient transparency—are ingredients, content, and origin clearly stated, plus a "free-from" list.

If any of the four is missing, be cautious.

Not entirely. CFU count matters, but three things matter more:

• Survival rate reaching the gut—probiotics lose viability through stomach acid, so encapsulation (e.g., microencapsulation) matters more than simply stacking CFU;
• Whether strains are targeted—different strains work differently; check for specific strains listed;
• Whether prebiotics are included—paired with prebiotics (e.g., FOS) they help beneficial bacteria colonize the gut rather than just "pass through".

PACKAR Saccharomyces boulardii Probiotic contains 285.6 billion CFU per box (23.8 billion per sachet), uses microencapsulation, and combines 6 strains, 4 digestive enzymes, and FOS prebiotic.

Four angles:

• Regular check-ups—blood tests for liver/kidney markers, recommended 1–2 times per year;
• Diet adjustment—control total protein but ensure quality protein to ease metabolic burden;
• Avoid medication abuse—especially human supplements and painkillers;
• Herbal support—consider products with Poria, Milk Thistle, Penthorum (e.g., PACKAR Liver & Kidney Support Tablets).

Consult a licensed veterinarian before any supplement—especially if the pet is already on medication.

• Vitamin A—related to feather powder and epithelial health; deficiency is common;
• Calcium—demand rises during molting and egg-laying; supplement with cuttlebone or mineral blocks;
• Quality protein—demand increases during molting;
• Strict contraindications: avocado, chocolate, onion, caffeine, alcohol are toxic to birds.

Mainly four points: diet (rabbits herbivorous, birds omnivorous/grain-leaning), metabolism speed (birds metabolize fast, need smaller doses), core nutrition (rabbits need Vitamin C and fiber, birds need Vitamin A and calcium), form (small pets prefer powder or granules to avoid choking on large pieces). Therefore cat/dog products cannot simply be downsized for small pets.

Yes, it deserves attention. Cats are strict carnivores with limited ability to synthesize some B vitamins on their own; and because B vitamins are water-soluble with little storage in the body, they are easily depleted by a monotonous diet, stress, or illness.

B-vitamin deficiency may show as reduced appetite, coarse coat, and lethargy. When supplementing, liquid form is friendlier for hard-to-pill cats and can be mixed into wet food.

Direct mixing is not recommended. Rabbits, parrots, cats, and dogs differ greatly in diet, metabolism, and contraindications: rabbits are herbivores sensitive to high-sugar fruits/vegetables; most birds strictly forbid avocado, chocolate, onions, etc. Dosing and form also differ.

Choose species-specific formulas (e.g., PACKAR Small Pet line: rabbit food, rabbit care, parrot food, parrot care).

• High-fiber hay as staple—maintains gut motility and teeth grinding;
• Vitamin C—rabbits cannot synthesize it and must get it from food;
• Calcium-phosphorus balance—avoid excess calcium causing urinary stones;
• Control vegetables, fruits, and treats—excess high-sugar produce easily causes digestive issues.

For specifics, refer to small-pet product instructions or consult an exotic-animal vet.

Start with three numbers: keratinase activity (U/kg), probiotic live count (CFU/kg), and whether the added form is stated. If a product only says "contains keratinase" without units, the level cannot be judged.

Take PACKAR's Herbal & Probiotic Rabbit Hairball Paste as an example. The guaranteed analysis (per kg) on the packaging reads: keratinase ≥50,000 U, Bacillus subtilis ≥6×10¹⁰ CFU, Enterococcus faecium ≥4×10¹⁰ CFU, fructooligosaccharides ≥1.5%, natural vitamin E ≥1,000 mg, moisture ≤50%. The symbol "≥" means the batch is guaranteed to be no less than that value — it is not an exact content.

Two things to check when reading the panel: ① keep the units complete (U, CFU, mg, %); ② confirm whether it is "per kg" or "per tube/bag" — the difference after conversion is large. See the Ingredient Encyclopedia for ingredient definitions.

They are 11 plant-derived sources such as oat hay powder, alfalfa hay powder, barley grass powder, dandelion powder, pumpkin powder, carrot powder and apple — their role is to give the gut "pushing power".

Rabbits cannot vomit, so swallowed fur can only leave together with the gut contents. Fiber pushes that content along so the fur leaves with the stool — instead of relying on oil to "slide" the fur out.

That also explains why this paste contains no mineral oil and no vegetable oil: it takes the combined route of "keratinase + plant fibers + probiotics" rather than the traditional oil-lubrication approach. See Buying Guide, Myth 6.

Start small, at a fixed spot, at a fixed time — most rabbits accept it after a few tries. Do not squeeze out a large blob at once.

Three practical moves: ① smear it on the rabbit's front paw or on a grass cake it likes and let it lick it off — the 30 ml syringe is graduated, so start with 0.5 ml; ② mix it into a small amount of its favourite hay or grass cake, not a whole bowl of staple food, or you cannot tell how much was actually eaten; ③ feed at the same time each day — forming a habit works far better than force-feeding.

If it refuses completely for several days, first rule out mouth and teeth problems (drooling, difficulty chewing, dropping food) and see a vet if needed; do not bribe it with lots of treats, or the paste loses priority.

It is not a quick fix: 2–3 times per week outside molting, increasing to 3–4 times a week — or even daily — during molting, and observe the stool for 2–4 weeks.

Reference doses (follow the packaging): outside molting — young rabbits (3–6 months) 0.5–1 ml per serving, 2–3 times a week; adult rabbits (>6 months) 1–2 ml per serving, 2–3 times a week. During molting — adult rabbits 2–3 ml per serving, 3–4 times a week; long-haired rabbits (>6 months) 2–4 ml per serving, once daily.

To judge whether it helps, watch three objective indicators: whether fur strands in the stool decrease, whether droppings return to normal size, and whether appetite and energy stay stable. If bloating, stopped defecation or refusal to eat appears, that is an emergency — see a vet immediately rather than increasing the dose.

Use it at the frequency stated on the packaging — it is a daily nutritional supplement. There is no such thing as a "rebound"; hairball management really depends on the daily base diet.

The recommended rhythm is "denser during molting, maintenance in between": use the molting dose in spring and autumn, and 2–3 times a week the rest of the year; long-haired rabbits (such as Angoras) benefit from a higher frequency all year round.

One reminder: the paste is the cherry on top — ample dried hay is the foundation. If the rabbit eats little hay and is never brushed, the paste alone cannot make up for it. Its 7 free-from claims (0 starch, 0 mineral oil, 0 fragrance, 0 chemical preservatives, 0 colourants, 0 artificial attractants, 0 artificial sweeteners) exist to reduce unnecessary metabolic load.

Yes, they pair well — together they cover "pushing fur out + gut environment + teeth-grinding fiber". Feed them at separate times rather than all at once.

A routine you can copy: morning — the hairball paste (dose by weight and molting stage); daytime — unlimited dried hay and clean water; evening — a grass cake as a reward and for teeth grinding; probiotics can be mixed into either meal.

Why separate them: mixing too much at once affects palatability and makes it impossible to tell what worked; feeding separately also makes stool changes easier to observe. If you use probiotics at the same time, do not dissolve them in water above 40°C. Ingredients and doses: hairball paste and grass cake.

The core difference is the approach: traditional pastes rely on oil to lubricate fur out, while this one takes the combined route of "enzymatic breakdown + fiber propulsion + probiotics".

Three points of comparison: ① lubrication vs propulsion — oil only lubricates physically and does not address the accumulation itself, whereas plant fibers make the digesta carry the fur along. ② whether it contains oil — this product contains no mineral oil and no vegetable oil; rabbits are hindgut-fermenting herbivores, and long-term high oil and sugar does not favour metabolic stability or gut flora balance. ③ whether there are verifiable figures — this product states guaranteed values such as keratinase ≥50,000 U/kg and live bacteria ≥6×10¹⁰ CFU/kg that can be checked item by item.

The naming matters too: it "pushes the fur out", it does not "dissolve fur inside the body" — worth stating up front to avoid mismatched expectations. See Buying Guide, Myth 6.

After opening, close it tightly and keep it cool and out of light; refrigerate in hot weather. Wipe the syringe tip after each use — do not wash the whole tube.

Key points: ① cool, dark and sealed, away from the stove and sunlight; ② refrigerate if you use it slowly or the weather is hot, and put it back promptly; ③ the 30 ml syringe is graduated — wipe the tip with a clean tissue after use so residue does not clump and affect the next dose; soaking the whole tube lets water in, which can breed bacteria and dilute the paste; ④ stop using it if there is a musty or off smell, separation or a swollen package, or if it is past its expiry date.

For general storage rules see FAQ, "How should supplements be stored after opening?".

The 88% is the combined share of three dried hays: Timothy hay 75% (USA) + oat hay 8% (Australia) + alfalfa hay 5%.

Why this ratio: Timothy is high in fiber and highly palatable, so it forms the long-term base; oat grass has good crude fiber and relatively low calcium, balancing the mix; alfalfa is higher in protein and calcium, so it is used only as a small supplement — long-term heavy intake of high-calcium hay by adult small pets raises the risk of urinary and soft-tissue calcium deposition.

The Timothy comes from the 47°N hay belt in the north-western United States. When choosing a grass cake, look first at total hay share + grass composition + origin, then at the process. See the Ingredient Encyclopedia, "Composite hay base".

They are blended across five directions: immunity (vitamin C + E), skeleton (vitamin D3 + calcium gluconate + calcium hydrogen phosphate), skin & coat (biotin + flaxseed oil + seaweed powder), gut (B vitamins + beet pulp + yeast cell wall) and growth (L-lysine + glutamic acid + trypsin).

In other words, it is not simply "hay pressed into a block" — it fills in the nutrient categories small pets commonly lack, then forms them into a hay-based cake.

With products like this, check whether the additive list is written out item by item (whether it names vitamin B1 / B2 / B6 / B12, D-biotin, yeast selenium and so on) instead of vaguely saying "multiple vitamins". The exact formula follows the product packaging.

The difference is nutrient retention: slow baking at low temperature preserves heat-sensitive vitamins and active compounds better, and the texture is softer and more palatable.

Conventional high-temperature air drying is usually 80–90°C: efficient, but heat-sensitive components (such as some vitamins) are lost to a greater degree. The grass cake's process chain is: harvested the same day → evenly chopped → blended with 18 nutrients → slow-baked at 65°C for over 12 hours → naturally cooled and sealed fresh.

When choosing, treat "temperature + duration" as a hard, comparable indicator — a product that says "low-temperature baked" without giving figures is of limited reference value.

Break them into small pieces and give one immediately after the action — that is the most effective use. For a picky eater, cut other treats first and make the grass cake the "only reward".

In practice: ① dose by weight (under 0.5 kg half a cake per serving; 0.5–2 kg 1–2 cakes; 2–5 kg 2–3 cakes; over 5 kg 4–5 cakes, split into 1–2 meals a day) and break one cake into 4–6 pieces for training, giving one piece at a time; ② for a picky rabbit, stop all other treats so the grass cake becomes the only reward — acceptance usually improves within a few days; ③ rewards must follow the action immediately, or the association is not formed.

Remember the positioning: a grass cake is a treat and cannot replace unlimited dried hay or species-specific staple food.

If it is damp and soft, or smells musty or rancid, stop feeding it — do not sun-dry it and use it again.

Storage: ① sealed, cool, dry and dark; after opening, put it in an airtight jar or clip the original bag shut; ② do not refrigerate (the temperature swings cause condensation and more dampness), and keep it away from the stove and balcony; ③ keep hands dry when taking pieces and reseal immediately.

Signals that mean stop: mould spots or a musty smell, oxidised oil smell (rancid), clumping from damp, a swollen package, past the expiry date. Natural hay ingredients vary slightly in colour by origin and batch — that is normal, and no cause for concern as long as none of the above appear.

Soaking is not recommended — one of the cake's values is the teeth-grinding effect of its hardness and fiber structure, and softening removes that.

On age: the product is labelled for rabbits / chinchillas / hamsters / guinea pigs 2 months and older; younger animals should stay on mother's milk or species-specific staple food, and a vet should be consulted before giving treats.

If a small pet is not drinking enough, the correct fix is to provide clean water separately (a bottle or bowl, changed often) rather than soaking cakes to add water. If you want to mix, crumble a cake over the hay as a topper, but do not leave it soaked for long — it spoils easily.

The division of labour is simple: the paste handles "can the fur move", the cake handles "teeth grinding + daily fiber and reward", and dried hay is the foundation for both.

A routine you can copy: all day — unlimited dried hay plus clean water; morning — the hairball paste, dosed by weight and molting stage; evening — a grass cake as a reward and for teeth grinding, dosed by weight (1–2 meals a day); during molting — increase the paste (adult rabbits 2–3 ml per serving, 3–4 times a week; long-haired rabbits 2–4 ml per serving, once daily) and brush daily.

The two do not conflict: the cake supplies crude fiber and teeth grinding, the paste supplies enzymatic breakdown, fiber propulsion and probiotics. Follow each product's packaging for exact doses.

Because alfalfa is high in calcium and protein — suitable as a phase supplement for young or nursing rabbits, but not for adult small pets in large amounts long term.

The daily staple for adult rabbits, chinchillas and guinea pigs should be based on high-fiber, relatively low-calcium hay such as Timothy: fiber maintains gut motility and teeth wear, and keeping calcium in check lowers the risk of urinary and soft-tissue calcium deposition.

So the formula is Timothy 75% as the base + oat grass 8% for balance + alfalfa 5% as a supplement. Conversely, if a grass cake is high in alfalfa and is fed as a daily treat, watch the total calcium intake. For related basics see FAQ, "What about the calcium-phosphorus ratio for chinchillas?".

Because the incisors of rabbits, chinchillas, guinea pigs and hamsters grow continuously — without grinding they become overgrown, which affects eating and can lead to dental problems.

Teeth grinding depends mainly on two things: ① high-fiber dried hay — the chewing and grinding motion is the main daily wear; ② food with hardness and fiber structure — such as low-temperature baked grass cakes, where the act of gnawing is itself a grinding session and is far more valuable than soft treats.

Signals to watch: drooling, dropping food, eating only soft items, exposed teeth, weight loss. If these appear, see an exotic-animal vet promptly — dental problems are not solved by changing treats.

Look at three things: hay share, whether nutrients are blended in, and the forming process — a treat made only of sugar and starch is empty calories.

Criteria: ① the higher the hay share, the closer to staple-grade (e.g. 88% hay); ② whether there is a defined nutrient direction (immunity, skeleton, skin & coat, gut, growth) rather than just "rich in nutrients"; ③ whether the process protects nutrients (low-temperature slow baking beats high-temperature quick drying).

Also keep the positioning straight: a treat is always a treat — it cannot replace unlimited dried hay or species-specific staple food; portion it by weight (grass cake reference: half a cake under 0.5 kg, 4–5 cakes for large breeds) so it does not overshadow the main diet.

The paste is only one link in the chain. What really works during molting is brushing + ample hay + environment management.

Checklist: ① brush daily — cut the amount of fur licked up at the source, especially for long-haired rabbits (Angora, Lionhead); ② unlimited dried hay — fiber drives the gut and carries fur out with the stool; ③ increase the hairball paste to the molting dose (adult rabbits 2–3 ml per serving, 3–4 times a week; long-haired rabbits 2–4 ml per serving, once daily); ④ check the stool daily — fur strands and smaller, harder droppings are signals; ⑤ reduce stress — cage changes, moving house and noise all affect appetite and defecation.

Red line: bloating, stopped defecation and refusal to eat are emergencies — see a vet immediately rather than increasing the paste.

The biggest difference: cats can vomit, rabbits cannot — so the two need completely different approaches.

Most cat hairballs can be vomited up or passed in the stool, and daily management centres on brushing, cat grass and an appropriate amount of hairball paste; if a cat retches frequently without producing anything, loses appetite or becomes lethargic, a vet visit is needed to investigate. Rabbits cannot vomit, so swallowed fur can only leave via the gut, which makes a high-fiber hay base and fiber-based support more important.

When buying: choose by species — do not give a rabbit's hairball paste to a cat (or vice versa), since formula, dose and palatability are all designed per species. See Buying Guide, "Dogs & Cats vs Small Pets: 4 differences in nutritional needs".

Keep it sealed, out of light and cool; refrigerate in hot weather. Stop using it if a strong fishy or rancid smell appears, or if the colour darkens noticeably.

Why: omega-3 are unsaturated fatty acids and oxidise readily on contact with air, light and heat; once oxidised they not only lose their supplement value but may add an extra burden.

In practice: ① seal immediately after use, do not leave it open; ② keep it out of light — not on a windowsill or beside the stove; ③ check the expiry date and packaging format — individual sachets or small sizes suit households with low usage; ④ formulas blended with antioxidants such as natural vitamin E are usually more stable. See the Ingredient Encyclopedia, "Fish oil / Omega-3".

Probiotics are the live bacteria; prebiotics are their food. The two work differently but are often used together.

Probiotics (such as Bacillus subtilis and Enterococcus faecium) directly add beneficial bacteria; prebiotics (such as fructooligosaccharides, FOS, and mannan-oligosaccharides, MOS) are not digested by the host but selectively feed the beneficial bacteria in the gut, helping them colonise rather than simply pass through.

So when choosing a product, check two things: whether the strains and live count (CFU) are stated and whether prebiotics are included. PACKAR's Saccharomyces boulardii Probiotic uses a combined formula of 6 highly active strains + 4 digestive enzymes + prebiotic FOS — see the product page.

A report is only verifiable when four elements line up: the testing organisation's name, the report number, the test items and the test date.

How to check: ① confirm the issuer is a third-party testing organisation; ② use the report number to verify authenticity on the organisation's website or through its service channel; ③ check that the test items match the claims (for example heavy metals, microbiology, ingredient content); ④ check that the report date matches the product batch.

PACKAR's test reports and qualification documents are published in the "Test Reports & Certifications" section of our website; if the section has not been updated yet, they can also be verified through customer service by email at micheal@ipackar.net.

One reminder: a claim that says "tested" without naming the organisation and the number is of limited reference value.

First distinguish two cases: seasonal shedding is normal, while nutritional shedding is what needs supplementation.

Nutritional shedding is usually linked to insufficient Omega-3, Omega-6 fatty acids, and B vitamins. Prioritize: deep-sea fish oil (provides Omega-3 / Omega-6) and B-complex vitamins (B1, B2, B6 support skin & coat metabolism).

Feed both together and continue for 4–8 weeks before re-evaluating—intermittent use has limited effect.

Note: if shedding is accompanied by redness, dandruff, or intense scratching, rule out skin disease or parasites first—supplements cannot replace diagnosis and treatment.

Both provide Omega-3 fatty acids; the difference is cost-effectiveness and absorption form. Deep-sea fish oil usually has higher EPA and DHA content and lower unit cost, suiting long-term daily use; krill oil's Omega-3 is in phospholipid form with theoretically slightly better absorption, but is generally pricier with lower unit content.

For value and long-term feeding, deep-sea fish oil is preferred; if a pet tolerates fish oil poorly or has weak digestion, try krill oil. Either way, pay attention to source of origin (e.g., Peruvian deep-sea waters) and whether vegetable oil is added as filler.

Lactoferrin is a multifunctional protein naturally present in mammalian milk; in pets it mainly participates in iron transport and immune regulation.

Common supplementation scenarios: weaning of young pets, seniors, and recovery during seasonal changes or post-surgery.

When choosing, focus on lactoferrin's source and content (e.g., imported from New Zealand), and whether it is combined with synergistic ingredients like IgG immunoglobulin, B-complex vitamins, and prebiotics. PACKAR Pet Lactoferrin uses a 4-factor formula with individual PTP moisture-proof packaging.

It depends on the category: nutritional supplements (fish oil, B vitamins, probiotics) can usually be used long-term at recommended doses; functional supports (urinary, liver/kidney herbal formulas) are best used in cycles and adjusted based on check-up results.

Either way, follow the recommended dosage, avoid stacking the same ingredient to excess, and regularly observe appetite, stool, and energy. For chronic illness or medication periods, consult a vet first.

Liquid form needs no disintegration or dissolution; its small-molecule structure enters the small intestine directly, is friendlier for pets with swallowing difficulty or weak digestion, and is less likely to choke—can be mixed into wet food.

Tablets offer precise dosing and easy storage/transport.

Neither is absolutely superior—it depends on the pet's age, swallowing ability, and feeding habits. PACKAR B-Complex Vitamin Solution is liquid form, 60 ML.

Generally take separately with time gaps, especially antibiotics, blood-pressure, or anti-seizure drugs. Some ingredients may affect drug absorption or metabolism.

For pets that are pregnant, young, or on chronic medication, consult a licensed veterinarian before supplementing.

• Cool, dry, dark, sealed—away from stove and sunlight;
• Liquid form—refrigerate after opening and use up soon;
• Moisture-proof—individual packaging (e.g., PTP) is more hygienic;
• Watch shelf life and changes in appearance (discoloration, off smell, clumping means discard).

Young pets: during weaning, focus on immunity (e.g., lactoferrin); introduce new foods at small doses. Pregnant or nursing pets: higher nutritional demand, but supplements need vet guidance to avoid affecting the fetus. Seniors: prefer liquid form for easy absorption; use liver/kidney support combined with annual check-ups.

Three checks: ① specific values and units (e.g., "285.6 billion CFU/box", "Omega-3 300mg/capsule") rather than vague words like "high content"; ② source of origin stated (e.g., Peruvian deep-sea fish, New Zealand lactoferrin); ③ third-party test report available (institution name + report number). The more transparent, the more trustworthy.

PACKAR currently has two main lines: Dogs & Cats and Small Pets. The dog/cat line covers skin & coat, immunity, gut, urinary, and liver/kidney scenarios; the small-pet line covers food and supplements for rabbits, parrots, etc. On the product page, switch to the "Small Pets" tab to match by species.

Common signals: fur in stool or matted stools, smaller/harder droppings, constipation, frequent dry heaves or coughing after grooming, bloating, lethargy, refusal to eat.

Rabbits cannot vomit; ingested fur can only leave via the gut, so daily ample dried hay plus fiber and probiotics during molting is key.

Reminder: bloating, stopped defecation, or refusal to eat are emergencies—seek veterinary care immediately; do not observe with hairball paste alone.

See PACKAR Herbal & Probiotic Rabbit Hairball Paste for ingredients and feeding chart.

No. Oil mainly provides physical lubrication and does not solve the accumulation itself.

Rabbits are hind-gut-fermenting pure herbivores that only forage grass and a little herbage in the wild, with limited ability to metabolize large amounts of oil and refined sugar; long-term high-oil/high-sugar feeding is bad for metabolic stability and gut flora balance.

A steadier approach is the combined " keratinase breaks down keratin + plant fiber pushes it out + probiotics maintain gut environment " plan. See Buying Guide · Myth 6.

Direct substitution is not recommended. Cats can vomit up hairballs, but rabbits cannot—ingested fur can only leave via the gut, a completely different physiological path.

When choosing, match by species and verify theapplicable age and dosage; chinchillas, hamsters, and guinea pigs should also use products labeled for their species.

PACKAR Herbal & Probiotic Rabbit Hairball Paste is labeled for rabbits / chinchillas / hamsters / guinea pigs 3 months and older.

Reference dosage: non-molting—young rabbits (3–6 mo) 0.5–1 ml/time, 2–3 times/week; adult rabbits (>6 mo) 1–2 ml/time, 2–3 times/week. Molting—adult rabbits 2–3 ml/time, 3–4 times/week; long-haired rabbits (>6 mo) 2–4 ml/time, once daily.

The product is a 30 ml measured syringe for clean, accurate dosing. Follow product packaging.

It cannot fully replace staple food. Cake is a supplement on top of unlimited dried hay, with ample water provided.

By weight: under 0.5kg, 1/2 cake per time; 0.5–2kg, 1–2 cakes; 2–5kg, 2–3 cakes; over 5kg, 4–5 cakes; 1–2 meals daily.

When choosing, check hay ratio, grass species, and origin plus the forming process (low-temp slow-baking better preserves nutrition).

See PACKAR Low-Temp Baked Nutrition Grass Cake (Small Pet).

It follows 7 free-from additives: 0 starch, 0 mineral oil, 0 flavoring, 0 chemical preservatives, 0 coloring, 0 artificial palatants, 0 artificial sweeteners.

It also contains no vegetable oil; the hairball approach is enzymatic breakdown + plant fiber + probiotics, not oil lubrication.

Yes, but wait until after weaning and strictly control the amount. Young pets generally start extra fish oil around 8 weeks, after stably eating puppy/kitten food; under 3 months is not recommended for self-supplementation.

Reference range: generally EPA+DHA about 20–50 mg/kg body weight/day; for a 3 kg kitten that is about 60–150 mg. This is a common industry range—follow product packaging and vet advice.

Two notes: during soft-stool/diarrhea, fix the gut first; fish oil has anticoagulant effects, so stop 1–2 weeks before surgery.

Usually once daily is enough; with food is steadier than empty stomach—food buffers stomach acid and helps live bacteria pass through to the gut.

During acute soft stools, temporarily increase to twice daily (morning and evening) for 3–5 days, then return to once daily for maintenance.

Water temperature matters: do not brew with water above 40°C or mix into just-heated food—high heat sharply reduces live-bacteria survival.

B vitamins are water-soluble, not stored in the body; excess is excreted in urine, so daily dosing at the labeled amount is common.

But two points: ① dose by weight and do not stack multiple B-containing products (e.g., B solution plus a multi-nutrient paste may duplicate); ② yellow-tinged urine is a normal B2 effect—no need to worry.

If the pet is on medication or has liver/kidney disease, consult a vet first.

Lactoferrin is nutritional support, not a fast-acting ingredient; usually evaluate after 2–4 weeks of continuous use.

It participates in iron transport and immune regulation; its effect is more about stable status during special periods (seasonal change, weaning, post-surgery) than short-term visible change.

Fix a time each day and feed continuously; pair with balanced staple food and rest for steadier results.

Yes, they work at different levels—fish oil for skin/coat and inflammation, probiotics for gut flora; no known conflict when co-fed.

In practice, separate time slots are better: e.g., probiotic with breakfast, fish oil with dinner—avoids overloading palatability at once and makes it easier to tell which is working.

One caveat: if the pet has diarrhea, add only probiotics first; resume fish oil after stools normalize (oil may worsen loose stools).

Yes; the common practice is "antibiotics first, then probiotics 2+ hours later." Antibiotics also harm beneficial gut bacteria while killing pathogens, so probiotics help flora recover.

Three keys: ① space at least 2 hours, do not feed together; ② after the course ends, continue probiotics 2–4 weeks to rebuild flora; ③ choose microencapsulated probiotics—coating improves survival through stomach acid.

If persistent vomiting or blood in stool occurs, see a vet rather than relying on supplements.

It depends, and you must ask the vet first.

① Pancreatitis: acute and early recovery phases usually require a low-fat diet; fish oil is an oil and generally paused until the vet decides to reintroduce after stabilization.

② Chronic kidney disease: EPA/DHA are often used in vet nutrition to support the kidneys, but dosing must be individualized—do not feed at ordinary maintenance doses.

Conclusion: both cases are therapeutic use; follow the attending vet's plan.

Yes, space them at least 2 hours. Some dewormers affect gut flora; spacing reduces interference.

Common practice: give probiotics as usual on deworming day but separate the two in time; if mild soft stools appear after deworming, continue probiotics 3–7 days to usually relieve.

If vomiting, lethargy, or blood in stool after deworming, it is an abnormal reaction—contact the vet immediately.

The core of stress soft stools is "reduce furtherirritation first, then add probiotics to nourish the gut."

Three steps: ① keep environment and diet unchanged—no new changes during moving, guests, or food switches; ② add probiotics, twice daily for 3–5 days during the acute phase; ③ short-term easily digestible staple, small and frequent.

Reminder: if soft stools last over 48 hours, with blood, lethargy, or refusal to eat, it is beyond supplements—seek veterinary care promptly.

Mild cases can be helped, but the root fix is "slow down the transition."

The right pace is usually the 7-day transition: days 1–2 old:new 1:4, days 3–4 2:3, days 5–6 3:2, day 7 fully new. Sudden full switch is the most common cause of transition diarrhea.

Support: during this period give probiotics daily (a formula with digestive enzymes fits better) to aid breakdown and absorption; if no improvement within 2 days, or vomiting/blood appears, pause the switch and see a vet.

First decide if it is physiological or nutritional, then decide on supplementation.

① Physiological shedding (once each spring/autumn, skin normal): ensure quality protein and essential fatty acids; during the molt, continuously feed fish oil (Omega-3 / Omega-6).

② Nutritional shedding (heavy year-round, dull coat): often linked to insufficient Omega-3, Omega-6, and B vitamins—pair fish oil + B-complex, continue 4–8 weeks before re-evaluating.

③ If accompanied by redness, dandruff, or intense scratching, rule out skin disease and parasites first; supplements cannot replace treatment.

The order is "get eating first, then supplement correctly"—do not pile on products at once.

① First priority is resuming eating—if the pet won't eat, any supplement is limited; start with a palatable staple;

② Second priority is the gut—post-surgery/illness often brings poor appetite and soft stools; probiotics help recovery;

③ Then immunity and energy—lactoferrin is often used for immune nutritional support during special periods (post-surgery, seasonal, weaning).

Special note: fish oil has anticoagulant effects; pause 1–2 weeks before surgery and during unhealed wounds; whether to resume is up to the attending vet.

Yes; foul stool and gas are usually an outward sign of "abnormal gut fermentation."

Troubleshoot by priority: ① diet too high in protein/fat, or sudden food switch; ② gut flora imbalance (manage with probiotics); ③ parasites or malabsorption (needs vet check).

Two things first: fix diet for 2 weeks + add probiotics (formula with digestive enzymes fits better). If soft stools and weight loss also appear, see a vet.

Yes. PACKAR Rabbit Hairball Paste lists rabbits / chinchillas / hamsters / guinea pigs amongsuitable animals, but dosage should be scaled down by weight.

The product is labeled for rabbits / chinchillas / hamsters / guinea pigs 3 months and older; dosage: young rabbits (3–6 mo) 0.5–1 ml/time, 2–3 times/week; adult rabbits (6+ mo) start at 1 ml.

Hamsters and guinea pigs weigh far less than rabbits—start at a small dose scaled to weight; confirm exact dosage with a vet.

Reminder: small pets expel ingested fur mainly via the gut, so daily ample dried hay matters more than the paste; for bloating or stopped defecation, seek veterinary care immediately.

Chinchillas are sensitive to Ca:P; the core principle is "not too much calcium, ratio roughly 2:1."

Common knowledge: the Ca:P ratio of herbivorous small-pet diets is usually recommended at 1.5:1 ~ 2:1. Chinchillas especially should avoid long-term heavy feeding of high-calcium hay (e.g., alfalfa), or risk increased urinary-tract and soft-tissue calcium deposition.

Practice: Timothy hay as the staple base (high fiber, relatively low calcium), alfalfa only as a phase supplement; with balanced species-specific food, extra calcium tablets are generally unnecessary.

If urination abnormalities or lethargy appear, see a vet rather than adding calcium yourself.

The key in molting is "high-quality protein + sulfur amino acids + trace elements," not random calcium.

Feather main component is keratin; molting nutrition focus: ① quality protein and sulfur amino acids (methionine, cysteine); ② B-complex vitamins for feather and energy metabolism; ③ zinc, selenium and other trace elements for feather-tube formation.

Practice: during molting provide balanced species-specific food + a little fresh produce; avoid seed-only feeding (high fat, incomplete protein). If feather-picking or uneven feather tubes appear, check parasites and environmental stress, and consult an avian vet.

Adult rabbits usually need no extra calcium; alfalfa is recommended only for young or nursing rabbits as a phase supplement.

Reason: alfalfa is high in both protein and calcium, suited to growing young rabbits; long-term heavy feeding in adults easily causes excess calcium intake and raises urinary-tract risk.

Practice: adult rabbits use Timothy hay as the long-term staple base (high fiber, aids teeth grinding and gut motility), oat grass as a pairing, alfalfa as a phase supplement. PACKAR Nutrition Grass Cake's hay base is Timothy 75% + oat 8% + alfalfa 5%.

If a rabbit shows urinary calcium or difficulty urinating, see a vet and adjust the diet rather than adding calcium.

It is the legally stated "guaranteed minimum or maximum content," not a precise value.

For example, "keratinase ≥50,000 U", "Bacillus subtilis ≥6×10¹⁰ CFU" — the ≥ means the factory guarantees no less than this at shipment; crude protein/fat often state "≥", moisture/ash "≤".

Two things when reading: ① see the unit and symbol clearly (U, CFU, mg/kg, ≥ or ≤); ② see whether it is "per kg" or "per sachet"—the converted difference is large.

Tip: the guaranteed analysis is a verifiable hard metric, more informative than vague adjectives like "high content."

Because the same product's dosage varies by species, weight, age, and purpose; the packaging is the authoritative applicable value.

Example: the same hairball paste differs for young vs. adult rabbits; the same grass cake differs in pieces per feeding for under 0.5 kg vs. over 2 kg. These specifics are only fully given on the physical packaging.

So: follow packaging first; for special cases (young, pregnant, ill, on medication) confirm with a vet—do not apply generic online numbers.

Microencapsulation puts a "protective shell" around live bacteria; the core effect is higher survival through stomach acid.

Oral live bacteria first pass through strongly acidic stomach; bare bacteria die in large numbers. After coating, the cells are wrapped in protective wall material, released upon reaching the gut—achieving "colonize the gut" rather than "pass through."

So when choosing probiotics, beyond total CFU (e.g., 285.6 billion CFU/box), also check strain types (e.g., 6 high-activity strains) and whether coating process exists—these three together determine the actual effective bacteria reaching the gut.

Slight batch differences in natural-ingredient products are normal, provided "within shelf life and not exaggerated."

Reason: plant extracts, fish oil, and hay ingredients naturally fluctuate with origin, season, and harvest batch; color depth and smell intensity may differ slightly; low-temp baking also does not unify color like high-temp processes.

When to be alert: ① moldy or rancid smell (oil oxidation); ② clumping, moisture, bulging packaging; ③ past shelf life. In these cases stop feeding and contact support.
