Can Cats Eat Tuna? – The Precautions

So why should tuna be given to your cat in small amounts?

The fact is, if tuna makes up too large a part of your cat’s diet, they could be missing out on essential vitamins such as vitamin E. This, in turn, can lead to malnutrition, and the onset of a condition called steatitic, (also known as a yellow fat disease). This causes inflammation of your cat’s fatty tissues and can be very painful.

Furthermore, tuna, especially the canned variety, contains a lot of mercury. This is a hazard of fish that are higher on the food chain and feed off smaller fish. Mercury builds up in the tuna’s body and is transferred to your cat upon ingestion.

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.

Too much tuna in a cat’s diet can also lead to a problem where the cat grows too fond of it. Tuna is full of flavor and is enjoyable food for your cat. This adds to the notion that tuna is best placed as a treat, rather than part of a staple diet.

Can Cats Eat Canned Tuna Fish – Extra Precautions

Cats and Canned Tuna Quality

Commercial tuna can range in quality, with a low range of fish generally being more detrimental to your cat’s health. It is these kinds of products that are more likely to be packed with cheap oil or brine.

Cats and Canned Tuna Ingredients

As well as the fatty oils and brine not being good for your cat, extra ingredients such as spices, tomato flavorings etc, are sometimes mixed into canned tuna. (This is a way of fleshing out the can with cheaper ingredients rather than actual fish meat). Again, these should be avoided as much as possible.

Healthy Tuna Cat Food

Many cat food brands have tuna as the main ingredient. However, Fussie Cat Tuna and Salmon Formula come highly recommended.

This wet cat food is crammed with vitamins as well as the amino acid taurine, which is essential to cats.

A small amount of tuna for your cat, whether it expensive fresh tuna or the cheaper canned variety (either for humans or as tinned cat food), is not going to harm your feline friend. In fact, the protein hit will be good for them.

However, stay away from the exotic ingredients and nasty oils and, as always don’t make a habit of feeding your cat one type of food.

A healthy balanced diet equals a healthy, happy cat after all.
