Cats are Carnivorous

From your high school biology, you know that cats are carnivorous mammals. This is to mean that they survive on meat. Now aside from being classified under the category carnivores, they also fall under a sub category known as obligate carnivores.

Animals in the obligate carnivorous category have to feed on meat in order to survive. Their digestive system is not designed to break down plant matter. In the event a cat does not consume sufficient proteins, its body will turn to its muscles. It will breakdown the muscles to generate the energy it needs to perform different tasks.

Contrary to popular belief, digesting plant matter is not a simple process. Herbivores have to reply on good bacteria to help in completing the digestion of plant parts consumed. And given the fact that plants tend to contain very low calories and nutritional value, they have to feed on a lot of plant matter to meet their nutritional targets.

Cats synthesize their glucose through a process known as gluconeogenesis. This is where the animal protein is broken down to produce glucose necessary for synthesizing energy.
