All  my 3 sister cats love it and my 2 older cats  love it too, "when they get a chance". Great instructions to follow so that made it easier for me to assemble. Very sturdy even without using stabliser at back of tree. Also received a spare ball and a couple of extra screws.
Delivery expected  by Wed but received it 3 days earlier on Sunday.
Well done Wayfair for a perfect transaction.
