I love the cat tree...and SHE loves the cat tree!  The only thing that's been a little bit of an issue is that it's not very weighted down on the bottom of the tree.  When she comes racing around the corner and jumps up on the tree (she won't use the ramp at all) then it tends to wobble and tottle.  It hasn't tipped over yet, thank heavens, but it is definitely tipsy.  The perch platforms are a little small, but she kinda has a big butt (like her mom) and she just has to curl up a little more.  OMG...she LOVES those mice that dangle down!    She will swat at those really hard and they go flying into the air.  I can hear her playing with it in the middle of the night.  I definitely think it's worth what I paid.  I am going to get a piece of plywood and see if I can't weight down the bottom a little more though.
