We, at the most, have one cat sleeping with us at a time. No dogs.......there just isn't room. Butter is a much better "bed fellow" because he sleeps at our feet (of course, you have to watch out if your toes stick out from the covers because they are bait for biting ). Mimi prefers to sleep on one's head, and Scott just can't handle that with his allergies. She rarely gets in the bed with us, as Butter is usually in our room (she prefers my daughter's bed), but when she does, it is my head she usually prefers and I get even less sleep than usual!!!!
