Actually mounting the design is very nice but unfortunately STILL a hut made for cats to small jigs ... My cat weighs 7 kg and who loves him climb up his usual hut refuses to go on this one And the reason is that when I put it up her legs tremble as the above do not support his weight and wobbles. The base is not stable either, and my cat do not feel reassured. Poor cushy even the right has a pretty cottage because of his size! When will manufacturers of products animals will adapt the design and comfort to the animals a bit beefy ??!
