Our big cat Ringo who is 13.5 pounds and really long body wise fits more comfy in this then the smaller store bought one. Im not sure if its because this one is square and all the others have been oval in shape but this one hands down is better. Only thing I would change if given the option would be to allow the buyer to choose between a carpet or rope covered for the front post that holds the bottom perch up. Most are usually covered in rope not carpet like this one.
 Would have created perfection covered in rope.
