Warning: Merck reports vitamin A toxicity in cats fed diets with a large amount of liver, with bony growths on the spine. Cooked, plain and only occasionally.

The Full Picture

Why Limited?

Merck reports that cats cannot convert beta-carotene to vitamin A and that hypervitaminosis A can develop in cats fed diets with a large amount of liver, causing bony growths on the spine with neck pain, stiffness and forelimb lameness. Reducing vitamin A stops further damage but does not reverse existing damage.

Merck reports that hypervitaminosis A can develop in cats fed diets with a large amount of liver. No source we checked gives a safe amount, so keep liver occasional and ask your veterinarian.

Preparation

How to Serve It Safely

Feed liver cooked and only occasionally as a treat or topper — it should never become a dietary staple given the vitamin A toxicity risk.

FAQ

Common Questions

Why is liver risky for cats?

Liver is very high in vitamin A, and Merck reports hypervitaminosis A in cats fed diets with a large amount of liver.

Is raw liver safe for cats?

Raw meat can carry bacteria such as Salmonella and E. coli (ASPCA). Cooked, plain liver, and only occasionally, is the more cautious choice.
