How are cats teeth different from human teeth?

A cat's teeth are designed to to hold down, kill and eat prey. The canines are very long in cats because these teeth help the cat hold on to its prey. They can also be use to kill the prey. Human canines are very blunt and are used to help tear meat.

Cats and humans both have premolars and molars, but a cat's back teeth are sharp and serrated and act like scissors; cutting up meat into bite-size chunks in order for the cat to swallow. A cat's jaw only moves up and down, so a cat cannot chew its food.

Human premolars and molars are grinding teeth, much like a herbivore. They are flat and our jaws can move side to side which aid in chewing our food thoroughly before swallowing.

The incisors in a human are the same size as all our other teeth and are primarily used for cutting food into bite-size chunks so we can chew it. A cat's incisors are very very small, and are mostly used for grooming.
