Bests & Worsts Reviews from Amazon

I read all of the negative reviews and what people are saying makes sense. It would obviously bow on a door without some sort of a strap in the middle. In addition, you would need to secure the door so it doesn't move every time the cat gets on and off of the unit. The instructions were poor, but in reality there's only 3 basic parts and anyone should be able to figure it out. The material on the platforms themselves looks like a padding material and is not carpet. The top and the bottom of the unit are capped with wood. The corners are not sharp as some people suggest. They are squared off corners covered in the padding material. There's nothing on the unit that would cut or injure the cat. I have one cat that weighs 14 lbs and he can go from platform to platform just fine. It would be easier for him if the platforms stuck out a little more. The other cat which is about 8 lbs, and loves climbing, goes up and down with ease. At first both cats looked confused and awkward going up and down the tree, but they quickly adapted and now they do it without effort. I planned on improvising the unit and mounting it to the wall and not a door. Because improvising it was in my plans, I ignored many of the negative reviews regarding it being wobbly. I drilled 3 holes, one on the top, one in the middle and one on the bottom of the unit. I secured it to a stud in the wall with a lag bolt on the top and the bottom. In the middle I used a lag with a loop on the end and then attached a toy to the loop. On the second platform there's now a toy dangling that the cat's can play with.
