Cats and Tuna – Why You Need To Be Careful

If your cat’s diet consists of too much tuna and becomes unbalanced, they could be missing out on essential vitamins such as vitamin E. A lack of vitamin E can lead to malnutrition, and the onset of a condition called steatitis, (also known as yellow fat disease). This causes inflammation of your cat’s fatty tissues and can be very painful.

Tuna also contains a lot of mercury, (especially in canned tuna). Tuna is high on the food chain, and feeds on other smaller fish. This means that Mercury builds up in the tuna’s body and is transferred to your cat when they eat it. Mercury is an element that has no natural place in your cat’s diet.

Tuna is also high in fatty acids and magnesium. While these oils (along with omega-3) are great for us humans, they have very little nutritional benefit for cats.
