i would like a cat just to keep the dog company. they don't work well for my early to bed habit because they like to play at night. 

when i shared a house with someone with cats, I would wake up and the kitten would be on my chest looking like she was plotting something nefarious. I could never tell if she looked at me like i was protecting her or if I was in her space. 

 yeah, cats out of the bedroom at night and two doors separated if they have got used to knocking (scratching) on the door, after 2 weeks with cat sleep cycle you are like a parent with newborn child for no reason, they have a 4 hour sleep cycle like infants
