I bought two of the Cat perches. My cat really love them. One of them was very wobbly so I tried to to tighten it and as I was turning it, it never got tighter, so I turned it upside down and realized that the hole was bigger than the screw. Now its 40 days after buying the cat perch. I really didnt think I needed a warranty from it, but Wayfair is doing nothing to replace it. Hopefully, I can find something out there on the market to put in the hole to make it
 smaller or get a bigger screw I dont know but I am disappointed
