Cats can eat cereal. Oatmeal contains a lot of dietary fiber, which helps cats digest and increase their appetite. However, oatmeal for human consumption may contain some additives and sugar, and oatmeal is single-nutrient and cannot meet the nutritional needs of cats. It is best to feed cats less oatmeal.

Precautions for cats eating cereal:

1. Eat in small amounts. Too much cereal can overtax your cat's digestive system, causing discomfort, vomiting, or diarrhea.

2. Avoid cereal cooked with milk. Many cats are lactose intolerant, meaning they lack the enzymes needed to digest milk, and cat cereal should only be cooked in water.

3. Nutritional combination. The nutrients contained in oatmeal cannot satisfy the daily life and growth and development of cats. Cats should be fed other staple foods such as fish, cat food, etc. while feeding oatmeal.
