🐈 Can My Cat Eat Liver?

Liver is packed with protein, iron, B vitamins, and vitamin A, making it a nutritious treat in small quantities. Most cats find liver irresistible. However, liver contains such concentrated levels of vitamin A that regular or excessive feeding can cause hypervitaminosis A — a condition where vitamin A accumulates to toxic levels. This leads to bone deformities, joint stiffness, and spinal fusion, especially with long-term overconsumption. A thumbnail-sized piece once or twice a week is a safe amount. Liver should be lightly cooked (not raw) and served plain.

Small occasional amounts: safe and nutritious. Regular overconsumption: vitamin A toxicity — bone growths on spine and joints, stiff joints, weight loss, lethargy, poor coat condition.

If your cat ate a small amount of liver, no concerns. If your cat has been eating liver daily for an extended period, consult your vet about vitamin A testing.

Plain cooked chicken breast, cooked fish, and commercial cat treats provide protein without the vitamin A toxicity risk.
