This is a classy castle for cats. I like the wood because it won't get hair embedded in it. The hammock and the cushion for the cubby are removable so you could wash them if needed. The cubby is a nice size - even my fat cat likes going in it. BUT there isn't carpet on the platforms and when the cats run and jump up on it the mostly fall right off because there isn't anything for them to dig their claws into. I might have to put down some velcro and some carpet remnants to give them something to hold on to.
