This cat tree is for small cats or kittens. It's well made and easy to assemble but my full grown cat can't use most of it. The three pedestal places on top only fit my kitten. Likewise the two bowls.  The hole at the top of the ramp is only 6" in diameter. The other problem with it is that, once the cat is at the third level, there's no easy way down.  I put a chair nearby for the kitten to jump to.
