Canned cats can be eaten overnight. If the ambient temperature is low or the canned cat is opened and placed in the refrigerator, it can still be eaten overnight. However, it is generally recommended that the canned food that is opened on the same day should be eaten on the same day. However, if it is not finished, you can seal the mouth of the can with plastic wrap and then put it in the refrigerator or outdoors below 0 degrees Celsius. It needs to be warmed up when feeding the cat again.

The dangers of cats eating cans that have spoiled overnight:

Because cans contain a lot of protein, leaving them overnight may cause bacteria to grow in the cans. Cats’ gastrointestinal tracts are relatively fragile, and eating a small amount of spoiled canned food may cause the cat to suffer from enteritis, causing vomiting and diarrhea. If a cat eats a lot of spoiled cans, it is very likely to get food poisoning, which can even endanger the cat's life in severe cases.

Once it is discovered that a cat has eaten spoiled canned cats, probiotics can be given to regulate the gastrointestinal tract in small amounts. In large amounts, vomiting can be used to prevent the cat from absorbing toxic substances, and the cat can be taken to a pet hospital for medical treatment in time.
