I have only had my two cats since december. They sleep in my bathroom. Its not tiny. Its 12 x 12 with a cat tree and all that jazz. My friend said its cruel to keep them in there at night. They never cry and they are out through the rest of the house all day. My husband is a very light sleeper and he would hear them playing. I cant sleep with my pets and they would want to crawl up on the bed. Where do YOUR cats sleep at night?
