I bought this hoping to deter my dog from getting into the litter box. The hole is large enough for my 65 pound puppy to stick his head in and feast. The top doesn't latch down and my pup can easily lift it up with his nose. I do like that less litter is spread around the floor due to top entry and holes for litter to fall back down. I will continue my search for the ideal litter box, but this will do for now.
