Cats cannot sleep outside the house because they need to protect themselves. In the wild, cats face a variety of threats, such as attacks from other animals, dangers from vehicles, hunger, and cold. Home is the safest place for cats, so they tend to stay home rather than go out and find new places to sleep. In addition, cats also have their own personalities and habits. Some cats like to move freely around the home, while others like to hide in a cozy place to rest.
Therefore, even if cats have the opportunity to sleep outside the home, they may not be willing to leave their familiar environment. In general, cats should not sleep outside the house to protect their own safety and preferences.
