I was excited to replace a well loved, but looking seedy climbing tree.  This one arrived and was a surprise.  My cat won't use it!  The round ledges are 12" without lips and the cubby is also 12" square.  His previous climbing tree had 24" perches.  The covering on it does not offer a good grip for his paws -- (it is not hook and loop carpet, like they normally use on climbing trees.)

Pros: Nice design
Cons: Too tiny for a secure jump, not wide enough to lounge on and nothing to grip onto when jumping up.
