Hi everyone. I'm new here. I have a question to all of you with cats that tend to get overweight. Someone told me about this cat feeder in which the cat has to work a little bit to get the food to drop, a few morsels at a time. I could have sworn she said she got it at petco but I can't find anything like that there or on petsmart or even amazon. This was a while back and I can't remember who told me about it (I've slept since then) to call and ask. But I do remember that her cat had lost a little weight since she got it. Does anyone have a feeder like this and where did you get it ?
