The only reason I didn't give this product five stars is because the back panel is not like the front and sides (no ribs just plain) so you can't turn it away from the front and have the cat enter from the back.  This not only would give the cat more privacy, but I have 2 dogs and it would keep them from getting to her when she doesn't want their company.  Suggest the manufacturer take this into consideration for a product update.

Pros: Very easy to assemble
Cons: Back panel doesn't match the other three sides.
