A suggestion: I recently purchased the 64" Faux Fur cat tree and found it to be unsteady and it topples over when the cats lunge onto it or off of it. Could I suggest that the bottom piece be made either larger or heavier to withhold the pouncing of 10 to 16 lb. cats? They love it and have a great time not only playing on it but sleeping on it also. however I don't think I would recommend it for larger cats, kittens yes!Sincerely, Grace
