Wow my kitties think this is absolutely Amazing!!! when they unwrapped it Christmas morning they could not believe their eyes. My senior kitty whom will be 21yrs old climbed right up into the enclosed cubicle and promptly decided to take a little nap and my 3yr old kitty decided it was play time on the top level and do a little bird watching :) The price on this could not be beat I know, because I shopped around at all those big Pet store places and the quality is outstanding. They also love the cat scratching posts strategically placed for them to stretch and scratch something we all know cats LOVE to do. My babies will enjoy this for a long time.
