My cats have never had a cat tree and this was their first! I ordered another bigger one, for I was not sure this would be big enough for both (they are each 12 lbs). This would have been enough! The tree is sturdy and enough room for both cats to be on. It is taller than I expected, but that is not a complaint! The only thing I would complain about is the carpet easily comes off and the colours I picked, it shows excruciatingly.
