This was an amazing product at a steal of a price - and free shipping!  My ONLY complaint (if you can call it that) is that the little circle on the top level is pretty worthless to a full grown cat.  I wish I had a kitten because a kitten would fit in it and probably freak out because it was stuck! Ha!  My cats LOVE the "bowl" - they literally wait for it to be available... purrrrr
