I brought this for my 4 adult cats, but I also foster kittens for a local rescue group.  My one adults likes to hide in the top hole while the kittens like to sleep in the paw on top. No matter the age of your cat or cats, they all find a spot on this cat tree.  I don't think they will ever get tired of it !! Plus it matches my furniture.  Love the brown 

Pros: very sturdy, and lots of spots for every size cat, love the color it does not show a lot of cat hair
Cons: NONE
