This cat tree is a little wobbly but it’s low enough to the ground for my 12 year old cat to get to easily. He prefers the higher tier. I was hoping the younger cat would be able to share and use the lower tier but they only use that as a step. They don’t play with the middle tier at all, but they aren’t kittens anymore, so not unexpected. The cats prefer a replaceable corrugated cardboard scratch post rather than the twine, so I had to buy that separately. Oh well, great for the money but could be a little sturdier.
