Medium-chain fats as a dietary energy source.
C8 and C10 describe the lengths of the fatty-acid chains.
Form Spray-dried C8/C10 powder

50 mg
Form Free-form L-arginine
An essential amino acid in feline protein nutrition.
Arginine belongs to the amino acids cats must obtain from their diet.
Form Free-form L-arginine
Established feline nutrition.
Four vitamins that help the body use nutrients.
0.75 mg
Form Thiamine HCl
A vitamin cofactor used in energy metabolism.
The active form of thiamine works with enzymes that process nutrients.
Form Thiamine HCl
NIH describes the biochemical role; Merck covers thiamine in feline nutrition.
0.5 mg
Form Pyridoxine HCl
A vitamin cofactor involved in amino-acid metabolism.
Pyridoxine is vitamin B6. Its active forms work with enzymes that process amino acids.
Form Pyridoxine HCl
NIH explains the biochemical role; Merck identifies cats’ dietary need for pyridoxine.
10 mcg
Form Cyanocobalamin (vitamin B12)
Works with folate in methyl transfer and cell metabolism.
B12 and folate participate in the conversion of homocysteine to methionine.
Form Cyanocobalamin (vitamin B12)
Nutritional function, distinct from treatment of B12 deficiency.
75 mcg
Form Pteroylmonoglutamic acid
A cofactor for nucleotide synthesis and dividing cells.
Folate participates in the chemistry used to make nucleotides.
Form Pteroylmonoglutamic acid
Established nutritional function.
Fiber, postbiotics, betaine and native collagen.
50 mg
Form Chicory root extract powder
Fermentable fiber for gut-microbial nutrition.
FOS is a prebiotic carbohydrate. Gut microbes ferment suitable fibers into short-chain fatty acids.
Form Chicory root extract powder
General digestive nutrition; combined-diet research is linked below.
250 mg
Form Betaine anhydrous powder
A methyl donor involved in metabolic reactions.
Betaine contributes methyl groups and also acts as an osmolyte, involved in cellular water balance.
Form Betaine anhydrous powder
Feline research studied betaine together with prebiotics in complete food.
1 × 10¹⁰ cell equivalents
Form Heat-treated Bifidobacterium animalis subsp. lactis
A non-live bacterial ingredient selected for gut support.
A non-live bacterial preparation. The serving is expressed in cell equivalents, not live probiotic CFU.
Form Heat-treated Bifidobacterium animalis subsp. lactis
Published feline findings are specific to the preparation studied; strain and preparation matter.
40 mg
Form Native chicken sternal type II collagen
Native type II collagen selected for joint care.
Undenatured describes collagen retaining its native structure. The amount is the standardized ingredient weight, not an assay of native collagen content.
Form Native chicken sternal type II collagen
The linked small trial involved arthritic dogs. It informs ingredient rationale, not a demonstrated joint benefit in cats.
Read the evidence
Study notes name the species, preparation and population so their limits stay visible. They explain ingredients or diets studied—not clinical validation, safety or efficacy of the finished Whisker9 formula.
Long-term feline research examined antioxidants, fatty acids and a prebiotic together.
The Cupp research followed 90 cats, aged 7–17 at entry, assigned to three diets. The combined diet was associated with differences in longevity and age-related health measures. This was a whole-diet result, not an isolated ingredient effect or a lifespan promise for this formula.
Purina Institute · study overview and Cupp references ↗A feline feeding study examined the safety and availability of EPA- and DHA-containing algal oil.
Vuorinen and colleagues studied gestation, lactation and kitten growth. Findings concern the algal oil and dietary levels tested, not adult-cat clinical outcomes or every algal preparation.
Vuorinen et al., 2020 · original study ↗A combined betaine-and-prebiotic diet changed selected metabolic measures in cats.
Hall and colleagues studied seven cats with chronic kidney disease in an eight-week crossover and 16 healthy cats over eight weeks. Body-mass improvement was reported in the kidney-disease group, not the healthy group. Betaine was studied with oat beta-glucan and short-chain FOS, not alone.
Hall et al., 2022 · original study ↗A short feline study measured gut-barrier, immune and microbiome responses to heat-treated bacteria.
Wang and colleagues studied 18 healthy adult cats in three groups for 28 days, using Bifidobacterium animalis subsp. lactis ZYhyy-003. The results describe that preparation and study period; cell-equivalent counts alone do not establish equivalence.
Wang et al., 2025 · original study ↗A small trial examined undenatured type II collagen in dogs with arthritis.
Deparle and colleagues studied undenatured type II collagen in dogs with arthritis. It is a canine ingredient study, not a feline trial and not a study of the finished Whisker9 formula.
Deparle et al. · canine collagen study ↗References explain nutritional functions and the ingredients or diets studied; they are not clinical validation of the finished Whisker9 formula.
These supporting ingredients are listed separately from the 17 actives above.
Chicken-liver, fish and organ-derived flavor ingredients.
Included to help protect the formula from oxidation.
A flow aid.
For adult cats of all ages. Not for kittens or pregnant or lactating cats. A supplement to a complete diet, not a replacement for food or veterinary care.
