Vitamin A Poisoning in Cats

3 min read


Many cats begin to recover as soon as the source of the vitamin A toxicity is no longer ingested, whether it be due to something in the diet (e.g., raw liver) or supplements. Your veterinarian can recommend a well-balanced diet for your cat's needs. To treat the pain, he or she may recommend painkillers.

Living and Management

The overall prognosis of this type of poisoning depends on the early initiation of treatment and the age of the cat. In mature cats, the symptoms usually resolve successfully, with the exception of the bone malformations. On the other hand, young cats can suffer from permanent damage to long bones which raise various other health concerns.

Periodic determination of vitamin A levels in the blood may be required to confirm the successful resolution of high vitamin A levels in the blood.


The best way to prevent vitamin A toxicity in cats is to consult your veterinarian before changing your pet's diet and/or starting it on a vitamin A supplement regimen. In addition, do not allow others to feed your cat without your permission, especially if the food contains liver.
