Used for only a month. No damage. Comes with the green and yellow hammock, unopened. The shelves and ramps have traction tape on them (it's like sandpaper) so the ramps aren't slippery. It also helps a little with keeping claws down. (it also does NOT have holes on the shelves like in the pic) You must pick it up. It will not be disassembled because I had to hammer some of the pieces together. ...
