I bought this cat tree as a Christmas gift for my adult sons kitten.  I put the tree together prior to my sons arrival for the holidays.  Every time I turned around, I found my 12 yr old cat inside the house!  I never thought he would use the house. He has his own tree on the screened porch but none inside so I decided to get him his very own cat tree.  After all, my old kitty is the best cat ever and hes worth it!Regarding the product, it is very stable, has a relatively small footprint, fits great in a corner or along a wall, by the window etc.  I like that the top perch is padded and has a border around three sides so my cat wont fall off in his sleep when he stretches.  The confirguration makes it easy for an older cat to use yet still intersting and fun for a younger kitten.  Shipping is fast.
