My cat is all over my bed every night. As I live in a loft, there is no bedroom door to close. She ultimately will sleep above my pillow near my head, after trotting around the bed. I know cats like to sleep in this location, close to their owners. However it's disturbing my husband because she doesn't care for him. He has even retreated to the couch some nights. Should I crate her at night? I don't like the idea but I have to change the bed linen every morning since she's walking all over it every night. Thoughts and suggestions welcomed. Thanks!
