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.
At a Glance
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 46% from chicken meal, soy protein isolate, egg, and pea protein to support lean body mass.
- Formulated to be complete and balanced for both growing kittens and adult cats, so it can be used long term if needed.
- Includes a select prebiotic fiber source to help support a healthy GI microbiome and digestion.
- St/Ox defense formulation is designed to promote a urinary environment less favorable to common crystal formation.
Considerations
- Contains chicken, egg, fish oil, and soy, which can be problem ingredients for cats with known food allergies to these proteins.
- At 3817 kcal per kg and 520 kcal per cup, it is an energy-dense food, so portions may need to be carefully measured to avoid weight gain.
- Uses several concentrated plant proteins, which contribute to total protein but are not equivalent to meat protein for some cats with higher animal-protein needs.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.

02
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.
03
Brewer's Rice
Brewer’s rice is a milling byproduct of rice processing made up of small broken white rice kernels commonly used in pet foods as a highly digestible carbohydrate source, filler and binder that provides readily available energy for dogs and cats while contributing little protein, fat or fiber. It is generally gentle on the stomach and cost‑effective, but diets using it must supply other ingredients for essential nutrients; pet owners should note its relatively high glycemic load (relevant for weight or diabetic pets), the potential for trace environmental contaminants associated with rice, and not confuse it with brewer’s yeast.
04
Egg Product
Egg product is used in pet foods as a high-quality, highly digestible animal protein and palatability enhancer, providing complete essential amino acids, fats, vitamins (such as A, D and B12), minerals and choline, and it often serves as a binder or emulsifier when included as whole, dried or concentrated egg. It supplies bioavailable nutrients for dogs and cats but can be a food allergen for some individuals, may be higher in fat depending on yolk content, and should be properly processed (pasteurized or cooked) to reduce microbial risk.
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.
