Bests & Worsts Reviews from Amazon

I like these. I solved a lot of the problems (for cats) by putting the roof on backwards (see pic.) Super heavy duty plastic. It would be 5 star if the tops actually snapped in place. As others reported they are easy to pop off. Im going to place these within a heavy fir tree which solves the problem for me. But if out in the open, a nut/bolt or gorilla glue would be good to hold it in one piece.
