When Betty was a puppy, she also loved those yummy, gross treats. We did the same thing with the baby gate. Our litter box is in the basement in a store room, so we put the baby gate in the hallway. When we installed it, we put the bottom of the gate about 8 inches or so off the floor, so the cat could go under it, but Betty couldn't. It works like a charm. I have to watched her like a hawk when I let her come out to the barn, however. It seems like she has traded her taste from cat poop to horse poop. The fresher the better.
YUK!
