Big cats can eat canned fish. Canned fish contains a lot of protein, water, and fat, which can be eaten by large cats to supplement nutrition. However, canned fish has a relatively simple nutritional content and can be eaten as supplementary food with cat food. It can be fed 2-3 times a week. The usual diet should be based on cat food. Cat food contains a variety of nutrients needed for the growth and development of cats, such as protein, amino acids, trace elements, vitamins, fats, water, etc., and the nutrition is relatively balanced.

Precautions for cats eating canned fish:

1. It is best to touch less canned tuna. Because tuna is at the upper end of the marine biological chain, its heavy metal content is relatively high, and the taste of tuna is relatively strong, which may easily cause cats and dogs to be picky eaters.

2. Eating too much green-skinned fish may cause yellow fat disease. Some fish have a green back, such as saury, tuna, mackerel, bonito, etc. Most of them contain a large amount of unsaturated fatty acids (EPA, DHA). If your cat eats too much of these green-skinned fish, it will cause A large amount of vitamin E is needed to break down these unsaturated fatty acids.

3. Pay attention to the toxic substances in cans. About 90% of pet wet foods on the market are mainly canned and canned. The inner layer of most cans will be coated with a protective layer, generally bisphenol A. This thing may cause harm to cats, because bisphenol A is an environmental hormone that has been proven to cause harm, such as affecting the reproductive system and development of cats and dogs, or causing mammary tumors, liver and kidney damage, etc. Therefore, it is better to choose staple food cans made of BPA-free material and send them to a third party for inspection. Those with SGS certification will be better.

4. The canned food must be eaten within two to three days after opening. Because the canned food has begun to deteriorate slowly after being opened. If it is stored for more than three days, the taste will be a little different.
