This is perfect for our Hyperthroid cat, who has been peeing inappropriately EVERYWHERE! It's part behavioral and part the disease. Introduced him to it slowly and within a day he was wanting to go into the crate. When not in the crate his peeing behavior has lessened significantly. The crate works great for a level for food and a sleeping place (we did extend the sleeping top shelf with a piece of wood for him to stretch out more comfortably). A hooded litterbox fits great on the bottom and we added a little stool for him to get to the second level. I've had a crate like this before many many years ago and this is a nice improvement. Has 2 gate openings, one on top and one on the bottom, rolls around great which will be crucial in winter as we'll want him in the warmest room. It is very very easy to put together and the shelves have felt lining so that cat won't slip on bare plastic. very impressed and worth every cent.
