Cats are generally capable of catching mice when they grow up, but their ability to catch mice depends on the type, age and health of the cat. Generally, adult cats have the ability to catch mice.
Cats usually start catching mice on their own in 3-4 months. Cats catch mice and eat them as food, which is usually taught by their mothers. When a cat is a month old, the mother of the cat will eat the mouse it catches in front of the kitten, which is to let the kitten understand that mice are a delicious food. After the kitten grows to two months, the mother of the cat will bring the mouse she caught for the kitten to eat.
In order to exercise the ability of kittens to catch mice, the mother cat will catch live mice for the kitten to play with. Gradually, the mother cat will not catch mice for the kitten, and will naturally catch mice when it is hungry.
