There is no fixed rule for how many times a cat should eat cat food a day. It usually depends on the size of the cat and its own nutrition to determine how many times a day it is most appropriate to feed the cat.

Cats at different stages have different digestive systems and nutritional needs, and cats’ feeding conditions will also vary. Generally speaking, adult cats only need to be fed 2-3 times a day. Kittens and older cats may need to be fed more often.

Overfeeding can also have many negative effects on cats’ health, with obesity being the most common problem. Excessive food intake causes the cat to consume more calories than it consumes, which will cause accumulation and lead to obesity. Overfeeding is very bad for the cat's health.

Cats are carnivores and need to consume sufficient nutrients such as protein and fat to maintain body functions. If the amount of food given is insufficient, malnutrition may result.
