There may be multiple reasons why cats sleep under the bed. For example, cats are naturally vigilant. As a hidden place, under the bed can provide them with a sense of security. This is a cat’s instinctive drive. Especially cats that have just arrived home may choose to hide under the bed to protect themselves because they are unfamiliar with the environment.

Secondly, cats may choose to sleep under the bed because they are afraid of being punished by their owners. When cats do something wrong, in order to avoid being scolded by their owners, they may choose to hide until their owners stabilize emotionally before coming out. This shows that the cat is smart and good at observing people's emotions.
