Friskies Tender and Crunchy Combo Dry Cat Food - Chicken, Beef, Carrots & Green Beans

Chicken by-product meal

Nutritionally it can be fine (organs are nutrient-dense), but the exact mix isn't disclosed and varies batch to batch, so quality is unpredictable.

Unnamed animal fat

Because the species isn't named, the source can change batch to batch — a problem if your pet has a protein allergy.

Animal digest

The source animal is never specified and it signals a formula relying on flavour coating rather than palatable ingredients.

Menadione (vitamin K3)

Banned from human supplements over liver toxicity and red-blood-cell damage at high doses. Still permitted in pet food, and there's no established requirement for supplemental vitamin K in healthy dogs and cats.

Artificial colours

Pets are effectively colour-blind to these distinctions — the dye exists to appeal to the human buying it. Some have been linked to hyperactivity in children and offer zero nutritional benefit.

Sodium metabisulfite

Destroys thiamine (vitamin B1). Thiamine deficiency is a serious, documented cause of neurological illness in cats.
