I got a couple of these cat feeding stations for Joe and Patch. They are both on special (and incompatible) diets, but the real trouble is that the new boys will steal their food in an instant if they have access to it. The feeders have a retractable cover over the bowl that opens when it senses their microchip and closes when they move away. It's going to take a while to get them used to these contraptions, but at least they are eating with the cover open (and boys confined elsewhere).
