Cats like to sleep in a comfortable environment. Cats develop a close relationship with their owners and feel that the most comfortable environment is around their owners.

Cats are very cold-sensitive animals and will sleep next to their owners when they feel cold. ​​​​​​

It may also be that they have lived with the owner for a long time and have great trust in the owner, so they will sleep next to the owner.

Cats may also be lonely. Although most cats are solitary, they will cling to their owners when there are no friends to play with.
