I had purchased a kitty cave in November that was causing competition among my 4 cats. Riley and Ray-Ray in particular were vying for the warmth of the cave, so I then ordered the Midnight Stars version. This prompted Naomi, the youngest cat, who is not quite 3 years old yet to claim it. Ray-Ray tries to use it when not in use by Naomi. It is so sweet to see any of the three cats cuddled up in the cave, or in particular when one of them peeks her head out as if to say "is it feeding time yet?" I highly recommend the kitty cave.
