Morphological characteristics:
A cat's body is divided into five parts: head, neck, trunk, limbs and tail. Most parts have fur, and a few are hairless cats.
Cats have fat pads at the bottom of their toes, so they walk quietly and don't run away when catching mice. They have pointed nails at their toes. Paws can be retracted and extended. Cats retract their claws when resting and walking, and only extend their claws when catching mice and climbing to prevent their nails from becoming dull. A cat has five fingers in its forelimbs and four fingers in its hind limbs.
