The main foods that American curl cats cannot eat include the following:

1. Milk. It is best not to give milk to American Curl kittens because milk contains high lactose content, which can easily lead to lactose intolerance and diarrhea.

2. Food with high salt content. American curl-eared cats are very sensitive to salt. If the salt content is too high, it can easily cause salt poisoning in American curly-eared cats, aggravate eye feces, and put a heavy burden on the kidneys.

3. Plants and flowers may cause poisoning in American Curl-eared cats, so do not let American Curl-eared cats eat them by mistake.

4. Foods such as chicken bones and fish bones can scratch the gastrointestinal tract or cause gastrointestinal blockage.

The best food for American Curl cats is cat food. Good cat food is rich in the daily nutritional needs of American Curl cats, so there is no need to feed other foods.
