Do you let your cats sleep in the room with you?

Our cat used to sleep with us and in our bed if she wanted to. In winter, she would sleep on our feet. It was very warm for us. In the morning, she would come to wake us up because she wanted food. We did not mind (or even think about) any problems with hair. During the day, she tended to sleep elsewhere though. Sometimes she would sleep in front of a window (if it was sunny). At other times, she would sleep either in a storage room or in the basement/coal cellar. I think she liked those places because they were dark and quiet. No one except her was able to get into them! She might also have been catching mice there but I am not completely sure about that. I know she used to bring mice and leave them in the bed for a while but eventually she stopped doing that. I do not know whether she stopped catching them or just stopped bringing them to show us. She also used to hide under the bed occasionally. I don't think she was sleeping there though. I think she went there because she knew we could not reach her there.
