WeruvaParis Sliving Sticks Tuna & Salmon Lickable Cat Treats

Fish with no species stated. The maker may use whatever is available, so the fish can change between batches. Nutritionally it is a fine protein and often a source of omega-3 fats. The gap is for pets with a known fish allergy, or whose owners are trying to track which protein causes a reaction, because an unnamed ingredient makes that very hard. Named fish such as salmon or whitefish give you that information.

A fish used mostly in cat foods, where its strong flavor is the point. Tuna is a good protein and a source of omega-3 fats. Two cautions apply to tuna fed often: it is higher in mercury than smaller fish, and cats can become fixated on it and refuse other foods. Both cautions apply to the cat eating tuna every day, and much less to tuna as one ingredient in a complete food fed in rotation.

A fatty fish used as a protein source and as a natural source of omega-3 fats. Fresh salmon is mostly water, so a salmon meal lower on the list may be contributing more protein. Salmon is a common alternative protein for pets that react to chicken or beef, though fish allergies exist too. Farmed and wild salmon differ in fat profile, and labels rarely say which.

Starch from the cassava root, used to bind kibble and as a carbohydrate source, especially in grain-free foods. It is nearly pure starch with little protein, fiber or micronutrients, and it is one of the least likely ingredients to trigger an allergy. A food that leans on tapioca for carbohydrate is getting easy digestibility and little else from it, which is fine as long as the rest of the recipe carries the nutrition.

The dried cells of yeast, often a by-product of brewing. It is rich in B vitamins, protein and minerals, improves flavor, and contains compounds that may support gut bacteria. Despite a persistent myth, there is no evidence it repels fleas. Yeast is an uncommon allergen in pets. Yeast culture is a slightly different product, a fermented feed that supplies similar nutrients.

A vegetable added in small amounts for fiber and a little flavor, and in fresh or raw recipes for its water content. It is safe for dogs and cats and appears well down the list, often alongside other vegetables in a blend. It brings almost no calories and only trace nutrients at these levels, so it changes nothing about the food either way.
