This is a little small for a full-grown cat. The height is great. So are the toy add-on parts. But my cat has a difficult time fitting in the cubby hole. The tiers are also flush between levels, so she has a difficult time getting up to the top tier. It would be a better cat tree if the platforms were somewhat staggered at different lengths allowing a full-grown cat to more easily get up & down. But the price & quality is great! I just don't suggest this one for larger cats. It would be better for kittens.
