Cats are not omnivores, but carnivores. Their main food source is meat, especially animal protein. While cats may eat some plant foods in some cases, this is usually not their primary food source. Cats are better suited to digesting and absorbing nutrients from animal foods.

In addition, cats' food choices in the wild environment are mainly small animals and birds. They have an instinct to hunt and prey on these animals, which is further evidence that cats are more likely to be carnivorous.
