I know the Surepet feeder works by microchip but it's not programmable to allow access to the food a a set time. I don't need food available all the time, just at a certain programmed time. Are there any other feeders out there for canned or raw food that are programmable and works by microchip? I have a regular programmable timed feeder but with two cats, I have no way of know who's eating the food.
