Tilapia & Tuna Hydrating Purée Supplement
Verified Jul 25, 2026
This is a canned tilapia and tuna purée designed as a low‑phosphorus supplemental food for adult and senior cats. It provides animal-based protein from fish and egg whites with added fats and oils for energy, in a very high-moisture texture to support hydration. It’s intended to be used alongside a complete and balanced diet, often for cats that need a phosphorus-restricted option under veterinary guidance.

Strong Choice
Nutritionally, this is a well-formulated, low-phosphorus supplemental food that can work nicely for adult and senior cats who need extra moisture and controlled phosphorus, such as many kidney-compromised cats, when used under veterinary guidance. Protein comes from clearly named, high-quality sources like tilapia, tuna, and egg whites, and the fat sources are also well-defined. It is not complete and balanced, so it must be combined with an appropriate full diet to avoid nutrient deficiencies over time.

Strengths
- Uses clearly named animal proteins (tilapia, tuna, egg white) as key ingredients, supporting lean muscle while keeping phosphorus lower than typical complete diets.
- Very high moisture (about 83.5%) can help support hydration, which is especially useful for cats that don’t drink much water on their own.
- Formulated specifically to be low in phosphorus, which may be beneficial for cats who require phosphorus restriction as part of their management plan.
- Contains defined fat sources (chicken fat, sunflower oil, fish oil) that provide essential fatty acids, and includes added taurine and vitamins for additional nutritional support.
Considerations
- Labeled for intermittent or supplemental feeding only and does not meet AAFCO minimums for phosphorus, so it cannot be used as a cat’s sole diet long term.
- Fish-based formulas can be problematic for cats with fish allergies or intolerances, and frequent fish feeding may not be ideal for every cat.
- Includes menadione sodium bisulfite (a synthetic vitamin K source), which is safe at regulated levels but is somewhat controversial among some pet owners and not required in all feline diets.

Top 5 Ingredients Explained
01
Fish Broth
Fish broth is used in pet food primarily as a flavor and moisture enhancer, providing modest amounts of fish-derived protein, amino acids, minerals and sometimes trace omega‑3s but not serving as a primary source of complete nutrition. It can improve hydration and entice picky, senior, or ill dogs and cats to eat, but caregivers should watch for high sodium, added seasonings (especially onion or garlic), potential fish allergies, and variable quality depending on processing.
02
Tilapia
Tilapia is a lean, easily digestible animal protein commonly used in dog and cat foods and treats, supplying essential amino acids along with modest amounts of B vitamins, selenium and some omega‑3 fatty acids. It can be a useful alternative protein for pets with sensitivities to common meats, but it generally contains fewer long‑chain omega‑3s than oily fish and should be responsibly sourced and properly processed to minimize contaminant or pathogen risks.

03
Tuna
Tuna is commonly used in pet foods as a highly palatable animal protein and flavor enhancer, providing readily digestible protein and omega‑3 fatty acids (EPA/DHA) along with B vitamins for both dogs and cats. While nutritionally beneficial, tuna can be high in mercury or sodium (especially canned), and feeding it exclusively or frequently may cause nutrient imbalances (including risks for thiamine or taurine issues in cats), so it should be offered in moderation as part of a complete, balanced diet.

04
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.
05
Chicken Fat
Chicken fat is used in dog and cat foods as a concentrated energy and flavor source that supplies essential fatty acids (notably linoleic acid) and aids absorption of fat‑soluble vitamins, improving palatability and supporting skin and coat health. Because it is calorie‑dense, diets must account for added fat to prevent weight gain, and quality (proper rendering and antioxidant protection to prevent rancidity) is important; although fats are less commonly allergenic than proteins, pets with poultry sensitivities may still react in some cases.
