Cats have fat pads at the bottom of their toes, so they don't run away when they walk silently to catch mice. They have sharp 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.
Living habits
Cats are agile, good at jumping, eating fish, pikas and so on. Cats like to eat fish and mice, because cats are Nocturnal Animals. In order to see things clearly at night, they need a lot of taurine, which is found in mice and fish.
So cats eat not only because they like fish and mice, but also because of their own needs. Cats, as natural enemies of rodents, can effectively reduce the harm of rodents to crops such as young crops, which can be seen from the serrated seedlings of cats in ancient agricultural life in China.
