My kitty loves his knee kitty tree house and provides him with lots of good exercise and play time. He drags many of his toys into to his little house. This also fits in beautifully and enables him the opportunity to watch all the birds and critters out the window. He first went to the great poles to sharpen his claws and mark his territory on his newest most interesting addition to hispart of our newly designed room. Will send photo when finished. He had been sleeping I his other SUV  Kittywalk stroller
