Cats, belonging to cats, are divided into domestic cats and wild cats, and are widely used pets in families all over the world. The ancestors of domestic cats are supposed to be desert cats in ancient Egypt and Persian cats in Persia, which have been domesticated by humans for 3500 years (but not completely domesticated like dogs).

morphological character

The cat's body is divided into five parts: head, neck, trunk, limbs and tail. Most parts are covered with fur, and a few are hairless cats.

Cats have fat pads at the bottom of their toes, so they walk silently, and they don't run away when catching mice, and they have sharp nails at the toe. The claws can be retracted and extended. Cats retract their claws when resting and walking, and only extend them when catching mice and climbing to prevent their nails from being dulled. A cat has five fingers on its forelimbs and four fingers on its hind limbs. Cats' teeth are divided into incisors, canines and molars.

Canine teeth are particularly developed, sharp as cones, suitable for killing caught rats, and the chewing surface of molars has sharp protrusions, which are suitable for chewing meat; Underdeveloped front teeth.
