kitten/now 4m cat uses the tree daily to rest and to imitate monkeys.  He destroyed the toys as soon as he reached 4lbs so thicker elastic is needed as he loves to play with them.  Doesn't use the boxes with holes much but more the perches.  It was easy enough to assemble without a carpenter/husband around.

Fabric was soft and all edges were smooth without any visible stables.  Only the chemical smell of the carpet bothered me.  Particularly because he chews on the carpet and licks it. Lots of carpets emit toxin depending on how they are made.
