Is it OK to Feed my Cat Tuna Fish?

First, there is the risk of mercury, which could build up in your cat's system over time. A cat that eats too much tuna may also develop nutritional deficiencies. After all, tuna alone can't provide all of the vitamins and nutrients your pet needs. The fish is especially lacking vitamin e, an important antioxidant. Without vitamin e, a cat could develop a condition called yellow fat disease.

So if you want to spoil your kitty, make him stick to a regular balanced diet, and only indulge his taste for tuna now and again.
