Our newest sleeper is only 24" tall but it has a lot to offer. The large 16" diameter sleep tub on top is just purr-fect for napping, sunning and pouncing on whoever is hiding in the tunnel down below. The Kitty Playground is just that... a kitten playground. Built (like all of our trees) for all the rough & tumble antics of kitty play!!! It's small enough for a busy house and big enough for your kitten's world. Feather toy optional. No assembly required.
