Animals eat a variety of foods, including plants, seeds, nuts and other animals, depending on the species of animal. Pet animals, such as dogs or cats, also eat commercial food in wet or dry forms.
Some animal species even choose to eat their own species. An example of this is the cheetah. Some cheetahs have been known to eat their young when the cub is weak or has something wrong with it, such as a deformity. Animals also eat their young if they do not have the food and the capability to care for the babies.
Pet animals have their food chosen for them by their owners. These animals may eat a variety of food, but most often have a commercial dry or wet food available to them. More exotic animals require a more detailed meal plan consisting of the foods that the animals eat in the wild naturally.
