If you get something that will be for multiple cats, it probably is a good thing, if it has any 'cubbyholes', that each one has two openings (so one kitty is not trapped in there, by another kitty who might be "play-prowling"!!! My friend just recently got me a berber one with a cubbyhole, and it does have an "escape" route at the one side, so the kitty inside, can get out the back entrance!! (I told her, "Now THAT was you, thinking like a kitty!!!" >^..^<
