Top Pick
This supplement is formulated to be added to your cat’s existing complete and balanced food, not used on its own. It focuses on extra animal-based protein, taurine, vitamins, probiotics, and digestive enzymes, which can be helpful for cats who may benefit from added digestive or nutritional support. It can be an option for healthy cats whose owners are looking to top up nutrients, as long as their main diet remains a complete cat food.

Strengths
- Very high protein content from animal sources like fish meal, chicken liver, and egg white powder.
- Includes added taurine, which is essential for cats and important for heart, vision, and overall health.
- Contains multiple probiotic strains and prebiotic fructooligosaccharides to support a healthy gut microbiome.
- Provides digestive enzymes such as amylase, protease, cellulase, and lactase that may help with food breakdown.
Considerations
- This is not a complete and balanced diet, so it must be used only as a supplement on top of a regular cat food.
- Fish and chicken are common allergens, so this may not suit cats with known sensitivities to those proteins.
- The high protein content is concentrated, so very small amounts are typically appropriate; following the feeding directions is important.
- As with any supplement, it’s best to check with your veterinarian before adding it for cats with medical conditions or on other supplements.

Top 5 Ingredients Explained
01
Fish
Fish is commonly used in pet foods as a highly digestible animal protein and an excellent source of omega‑3 fatty acids (EPA and DHA) that support skin and coat health, joint function, and cognitive development in both dogs and cats. It also supplies B vitamins and minerals but can be a common allergen, may contain environmental contaminants or mercury depending on species and sourcing, and raw fish can contain thiaminase—so choose properly processed, nutritionally balanced, and sustainably sourced fish ingredients.
02
Chicken Liver
Chicken liver is a nutrient-dense organ meat commonly used in pet foods and treats as a highly palatable protein source and flavor enhancer, providing concentrated vitamins (especially vitamin A and B-complex), iron, and copper that support energy metabolism, red blood cell formation, and skin/coat health in both dogs and cats. Because it is so rich, liver should be fed in moderation—excessive intake can cause vitamin A toxicity, and its high fat content and risk of bacterial contamination mean it should be properly sourced or cooked and limited for pets with pancreatitis or specific dietary restrictions.
03
Egg White
Egg white is a highly digestible, low‑fat, high‑quality protein source in pet foods, supplying concentrated albumin and essential amino acids that support muscle maintenance and growth in dogs and cats. It provides a lean protein alternative to meat but lacks the vitamins and fats of the yolk, can be an allergen for some pets, and raw egg white contains avidin (which can interfere with biotin) and may carry salmonella risk, so cooked or pasteurized forms are preferred.
04
FOS
Fructooligosaccharides (FOS) are non-digestible, soluble prebiotic fibers commonly added to pet foods and supplements to feed beneficial gut bacteria and support intestinal health. In dogs and cats they can help improve digestion, stool quality and immune support, but excessive amounts may cause gas or loose stools in sensitive animals so levels should be balanced and introduced gradually.
05
Taurine
Taurine is an amino sulfonic acid added to pet foods to support essential functions such as heart muscle performance, retinal health, and reproduction, and is particularly critical for cats, which cannot synthesize enough on their own. Adequate taurine prevents conditions like dilated cardiomyopathy and vision degeneration—dogs generally make more taurine but certain breeds or homemade/vegetarian diets may require supplementation—so commercial diets should meet species-specific levels and homemade plans should be carefully supplemented.
