Query: Just what I needed

Since I rent, I couldn't put a hole in anything. This was the perfect solution. Some people have mentioned that the weather stripping was inadequate, and I can understand that. I bought some additional stripping myself, but what came with it was decent quality. Much will depend on where you live.I don't have to mess with litter boxes anymore, and my cat is very happy.
