If it is an adult cat, it may be a sign of estrus, usually accompanied by shouting and other body movements; if the cat walks in front of you and suddenly lies down and exposes its belly, it may be coquettishly coquettishly asking for a pet; the cat is feeling the heat. The cat will also make this action when the cat is sleeping, which can cool down; in addition, the cat has four paws pointing upward, which means it is ready to attack.
