honestly wasnt sure if this would be big enough for my 15lb tabby but its MASSIVE. fits right in the corner like it said. the assembly took me like 45 mins cuz i kept putting one of the poles in wrong lol but once it was up its sturdy as heck. the top platform is actually padded which is nice cuz most are just hard wood under thin fabric. 10/10 recommend if u have big kitties.
