A small bit of liver is OK, but too much liver might induce vitamin A poisoning. This is a dangerous ailment that can cause your cat's bones to deteriorate. Deformed bones, bone growth on the elbows and spine, and osteoporosis are all symptoms. Toxic levels of vitamin A can potentially result in death. Therefore, only treat your cat if she actually eats some of her own liver. Liver consists mainly of protein and iron. The most common dietary problem with cats is poor quality food which causes them to lose weight even though they are eating. Fatty foods are not good for cats because they contain high amounts of cholesterol. Liver contains large amounts of vitamins A and C as well as minerals such as copper, phosphorus, potassium, and zinc. Eating too much liver can be toxic to cats so always feed your cat only fresh meat, without additives or preservatives. Cats should never drink water from dirty sources so ensure that any water source you provide for your cat is clean. Even better, provide your cat with his own special drinking bowl so he does not need to drink from public sources. Cooked liver is safe to feed to cats although it is best if you avoid feeding it to an adult female with kittens since it may lead to vitamin A toxicity. If your cat starts eating too much liver or anything else wrong, then see your vet right away so something can be done before any serious damage occurs.
