Using molars to chew food and then swallow it is the eating method of omnivores, including us humans. Herbivores, on the other hand, move their jaws left and right to "grind" the food before swallowing it. Carnivores generally swallow their food directly without chewing it, so we can't see them chewing. ​​​​​​

You can observe the shape of the molars while your cat is yawning. Our human molars are called molars because the teeth are in the shape of a molar, while the front ends of cat molars are pointed. This shape makes it impossible to chew. Next, when the cat closes its mouth, open its lips, and then observe the molars at this time. You can find that the upper molars and the lower molars are "staggered" and cannot "bite" together like our molars. At the same time, it turns out that even if you want to chew it, you can’t chew it.

Cats use molars to "tear" meat into a size suitable for swallowing, and then swallow it. This is the orthodox way of eating, because molars are used to "tear" food. So it must be pointed and staggered. We simply use our front teeth to bite food into appropriate sizes. The front ends of human incisors are pointed and staggered forward and backward. This is the same principle as using scissors to cut things. Cat's molars are called "carnivore teeth."

Cut a piece of sashimi and throw it to the cat to try. It must be across the head, chew it with the molars for two or three mouthfuls, and then swallow it. The two or three mouthfuls are just tearing the fish fillet into a suitable size, not chewing it, so Cats eat very quickly.

For cat food, there is no need to bite, just grind it with your front teeth. Originally, a cat’s tiny incisors were of no use. The incisors were mainly used for licking and cleaning body hair, and for scratching.
