Wx Phos Focused Lickable Tuna Cat Treat
Verified Jun 14, 2026
This is a lickable tuna-based paste treat for adult and senior cats, designed to be very palatable while staying low in phosphorus. It uses tuna, egg white, and fish broth as key protein sources and is high in moisture, which can help support hydration. It’s intended as a supplemental treat, not a complete diet, and may be useful for cats who need to limit phosphorus intake as directed by a veterinarian.
Nutritionally, this is a thoughtfully formulated, low-phosphorus treat that can work well for adult and senior cats, especially those who need phosphorus restriction and still enjoy tuna flavors. The recipe focuses on animal-based proteins from tuna and egg white, with very low ash and phosphorus levels for a treat. It should be used alongside a complete and balanced main diet and under veterinary guidance if your cat has kidney concerns.

At a Glance
KibbleLab Review
Strengths
- Tuna, egg white, and fish broth provide animal-based protein sources rather than relying on plant proteins.
- Very low phosphorus (max 0.05%) and low ash (max 1.5%) for a treat, which can be helpful when you need to limit phosphorus intake.
- High moisture content (up to 84%) can contribute to your cat’s overall water intake.
- Moderate calorie density (about 14 kcal per treat) makes it easier to use as a small, flavorful topper or reward without adding excessive calories when fed appropriately.
Considerations
- This product is not complete and balanced and is specifically labeled as not meeting full phosphorus requirements, so it must only be used as a treat or topper alongside a complete diet.
- Tuna and fish oil mean this is not suitable for cats with fish allergies or sensitivities.
- Contains egg white, which can be an allergen for some cats with egg sensitivities.
- Because it’s designed for lower phosphorus needs, it’s best used under your veterinarian’s guidance if your cat has kidney or other medical conditions.

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
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.
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
Sunflower Oil
Sunflower oil is used in pet foods as a concentrated fat source to increase energy density, palatability and supply linoleic acid (an essential omega‑6) that helps maintain healthy skin and coat. It is beneficial for dogs and cats but is high in omega‑6 and low in omega‑3—so formulas should balance fatty acids to avoid an inflammatory imbalance; it is calorie‑dense (important for weight control and pancreatitis-prone animals) and may require antioxidants or high‑oleic formulations for better shelf stability.
05
Tapioca Starch
Tapioca starch is a purified carbohydrate used in pet foods mainly as a thickener, binder and easily digestible energy source, contributing virtually no protein, fat, vitamins or minerals. It is low‑allergy and gluten‑free, but because it is a high‑glycemic, low‑nutrient filler it should be limited in diets for overweight or diabetic pets and not relied on for essential nutrition.
