Yes, in tiny amounts. Liver is a nutrient-dense treat that becomes harmful if overfed.

Why it’s a sometimes-food

Liver is packed with vitamin A, iron and B vitamins, and most cats find it delicious. The catch is vitamin A: chronic overfeeding causes hypervitaminosis A, leading to painful bony outgrowths and stiffness, especially along the neck and spine.

How to serve it safely

Offer a thumbnail-sized piece of cooked liver once a week at most, mixed into regular food.

Warning signs to watch for

Long-term overfeeding leads to stiffness, reluctance to jump, a fussy appetite and deformed bone growth; a sudden large serving can cause vomiting.

When to call the vet

If liver has been a regular part of the diet and your cat moves stiffly, ask your vet to check vitamin A levels.

Common questions

Is liver in commercial cat food a problem?

No. Complete foods include liver at safe, balanced levels — the risk comes from adding extra on top.
