I got my first one 7 years ago and it is still usable. I had to tape the top due to some of my cats sit and scratch on top, but it is still great and currently on my front porch for a feral neutered female. These are great outside, I have one in my shed, one for my finicky tabby, she uses it every day. I got a back up just in case. These are great, the cats love them and the hold up very well and are a good price.
