Verified Aug 26, 2026
This is a high-protein, highly digestible dry veterinary diet designed for kittens and adult cats with gastrointestinal issues. It relies on concentrated soy and poultry by-product meal for protein, with added fish oil for omega-3s and B vitamins for extra nutritional support. The formula is energy-dense, so cats can get plenty of calories and nutrients from relatively small meals.

This is a therapeutic diet, formulated for a specific medical condition under veterinary direction. KibbleLab does not assign it a general wellness score, because a therapeutic diet's nutrient targets are set clinically, not by maintenance standards. Your veterinarian selects the right therapeutic diet for your pet.

Where these benefits come from
Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Very high protein at 50% minimum, which suits the carnivorous needs of kittens and adult cats when tolerated by their GI tract.
- Formulated to be highly digestible and energy-dense, which helps cats get more nutrition from smaller portions.
- Complete and balanced according to AAFCO for both kitten growth and adult maintenance, so it can be used long term if needed.
- Includes fish oil and added B vitamins, which can support skin, coat, and overall metabolic health.
Considerations
- Primary proteins are soy-based and poultry by-product meal, which may not suit cats with soy or poultry sensitivities.
- The calorie density is high, so careful portion control is important to avoid unwanted weight gain in less active cats.
- This is a therapeutic GI diet, so it’s best used under a veterinarian’s direction rather than as a general everyday food for healthy cats.

Top 5 Ingredients Explained
01
Soy Protein Isolate
Soy protein isolate is a concentrated plant-based protein derived from defatted soy and is commonly used in dry and canned pet foods as a protein source, binder and texturizer to boost crude protein and improve kibble structure. It provides substantial protein and some essential amino acids but is generally less bioavailable than animal proteins and low in taurine (a concern for obligate carnivores like cats); some pets may be allergic to soy and soy contains phytoestrogens, though most anti-nutritional factors are reduced during processing, so consult your veterinarian for diets relying heavily on plant proteins.
02
Poultry By-Product
Poultry by-product is used primarily as a concentrated protein, fat and micronutrient source in pet foods and consists of rendered poultry parts such as internal organs, bones and connective tissues that supply amino acids, minerals (notably calcium and phosphorus) and B‑vitamins. It can be a cost‑effective source of bioavailable nutrients, but composition and quality vary by source and processing—owners of pets with poultry allergies or who prefer named-meat ingredients may choose alternatives, and safety depends on reputable rendering and adherence to regulatory standards.
03
Corn Protein Meal
Corn protein meal is a concentrated plant-based protein ingredient commonly used to raise crude protein and energy in dry kibbles, treats and some wet diets as a cost-effective alternative to animal protein sources. It provides digestible amino acids for dogs but has an incomplete amino acid profile (notably low in lysine and lacking taurine), so it should be balanced with higher-quality animal proteins for growing animals and obligate‑carnivore cats; some pets may also be sensitive to corn and quality/sourcing can affect safety and nutrient content.
04
Soy
Soy is a plant-derived ingredient commonly used in pet foods as a protein source and provider of carbohydrates, fiber and some fats (depending on the form), typically included as soybean meal, concentrate or isolate to boost protein and caloric density; dogs generally digest soy protein acceptably, while cats—being obligate carnivores—need animal-derived proteins for certain nutrients like taurine and should not rely on soy as a primary protein. Benefits include cost-effective, digestible protein and added fiber and micronutrients, but soy is a known allergen for some pets and contains phytochemicals and anti-nutritional factors (largely reduced by processing) that could affect thyroid or hormone-sensitive animals, so its use should be in balanced formulations and monitored if concerns arise.
05
Animal Fat
Animal fat is used in pet foods as a concentrated energy source and palatability enhancer, and can provide fat-soluble vitamin absorption and essential fatty acids (including arachidonic and linoleic acids, depending on the source) that support skin, coat and overall cellular function—particularly important for obligate carnivores like cats. Because it is calorie-dense and prone to oxidation, fats are typically rendered and stabilized; owners should be aware that high-fat diets can contribute to obesity and may trigger pancreatitis in susceptible dogs, so quality, source, and total dietary fat should be considered.
