The reasons why orange cats like to sleep with people:

1. If a cat lacks a sense of security, it will like to sleep with people, which will make it feel at ease. Always be alert.
2. Cats are relatively lazy animals. They like to lie in a comfortable place to sleep, and they like to sleep with their owners. It may be that the owner's bed makes them feel very comfortable.

3. When the weather is cold, cats will like to sleep with their owners in order to keep warm.

4. When a cat regards its owner as a relative, it will worry about the owner's safety and want to sleep with the owner to protect the owner.
5. Cats are very sensitive to smells. If they like the smell of their owners very much, they will like to sleep with them.
