WeruvaWx Phos Focused Chicken Lickable Cat Treats

The most common protein in pet food, and for dogs one of the most common food allergens, with beef and dairy. If chicken is what your pet reacts to, it hides everywhere: chicken fat, chicken broth, chicken meal, natural flavor. On a label, chicken listed first is weighed with its water still in, so a food leading with fresh chicken often has less chicken protein than one leading with chicken meal. Neither is better; they are different measures.

Rendered fat, a concentrated energy source and the main supply of linoleic acid, an essential fatty acid for skin and coat. Rendered fat carries very little protein, so many chicken-allergic pets tolerate it, but not all do, and a strict elimination diet avoids it. Usually preserved with mixed tocopherols. Not a quality concern; a good fat source.

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.

Oil pressed from whole fish, usually menhaden, herring or sardine, added as the source of the omega-3 fats EPA and DHA. Those fats support skin, coat, joints and brain development, and a food that names fish oil is delivering them in the form pets use directly. It goes rancid quickly, so look for a preservative named alongside it, usually mixed tocopherols. The species is rarely stated, which matters only if your pet reacts to fish.

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.
