The papillae from backward-facing hooks containing large amounts of keratin, the same material found in human fingernails. The hardness and strength of these hooks helps the cat to hold prey. The hooks also provide the abrasiveness that is so effective when a cat groom itself.

On cat's tongue, it contains 2 sets of taste buds. due to that, it makes cats to have extremely sensitive in taste. Cats are unable to taste sweetness. Cats tongue also reacts to temperature. That explains why cats do not like too hot food, or food that is too cold. They prefer food to be served in room temperature.
