Can Cats Eat Liver?

Yes — plain, cooked liver can be safe for cats in small amounts. But liver is extremely rich in vitamin A, so too much or too frequent feeding can cause serious vitamin A toxicity in cats.

Liver can be a treat, but too much is risky for cats

Liver is an animal protein, so it fits a cat's carnivorous diet better than many human foods. However, cats are especially prone to hypervitaminosis A when liver is fed regularly or in large amounts, and raw liver also carries bacterial risks, so liver should only be an occasional, small, cooked treat.

How urgent is this?

Emergency

Go to the ER now

  • ● Cat is having trouble breathing, collapsing, repeated vomiting, seizures, or severe lethargy after eating liver or a liver-containing supplement
  • ● Cat got into a large amount of vitamin A-rich supplements such as cod liver oil or concentrated vitamin products
Urgent

See a vet within 24 hours

  • ● Cat ate a very large amount of liver at once and now has vomiting, diarrhea, belly pain, or will not eat
  • ● Your cat has been fed liver frequently over weeks to months, especially as a major part of the diet
  • ● You notice chronic signs that can fit vitamin A toxicity, such as neck pain, stiffness, reluctance to jump, decreased grooming, or forelimb lameness
  • ● Cat ate raw liver and is now showing GI signs or seems unwell
Monitor

Watch at home, call if it worsens

  • ● Cat ate a small amount of plain cooked liver and is acting normal
  • ● Cat had a few tiny pieces of liver as an occasional treat with no symptoms

How to Safely Feed Liver to Your Cat

If you offer liver, keep it plain, cooked, and very limited. Liver is nutrient-dense but should not replace a complete and balanced cat food, and it should not be fed often enough to become a significant part of the diet.

  • Serve only small amounts as an occasional treat, not a daily food
  • Feed plain cooked liver with no onion, garlic, salt, butter, sauces, or seasoning
  • Avoid raw liver because of bacterial contamination risk
  • Cut into tiny bite-size pieces to reduce stomach upset
  • Do not use liver as a major part of a homemade diet unless your vet formulates the diet

Common Questions

Is liver good for cats?
Liver is rich in protein, iron, and several vitamins, so it can be nutritious in tiny amounts. The problem is that it is extremely high in vitamin A, and cats can develop hypervitaminosis A if liver is fed too often or as a large portion of the diet.
How much liver can a cat eat?
There is no universally published veterinary serving rule for liver treats in cats, so the safest approach is to keep it to a very small amount only occasionally and make sure treats do not unbalance your cat's complete diet. If you want to feed liver regularly, ask your veterinarian for guidance.
Why are cats at risk from too much liver?
Cats are particularly known for developing vitamin A toxicity when fed liver-heavy diets over time. Merck Veterinary Manual notes that cats fed excess vitamin A, usually from diets consisting largely of liver, can develop bony changes in the spine along with neck pain, rigidity, and forelimb lameness.
What are signs of vitamin A toxicity in cats?
Chronic vitamin A toxicity in cats can cause neck pain, stiffness, reluctance to move normally, reduced ability to groom, and forelimb lameness. Acute excess from vitamin A-rich products may also cause signs such as anorexia, weakness, tremors, seizures, or vomiting. Call your vet promptly if you notice any of these signs.
Is liver safer for cats than dogs?
Both cats and dogs can eat small amounts of liver, but cats are a classic species for developing hypervitaminosis A from liver-heavy diets. That means liver should be treated especially cautiously in cats, and it should never become a major part of their regular feeding plan.
