Doc & Phoebe's Hunting Feeder cat feeding system. Contains 3 adjustable feeding mice, a trainer, and a portion filler scoop. Designed to feed your cat in an engaged way. We used only for a couple of weeks as our cat has special diet food that is much larger than regular kibble (almost 3x) that would sometimes jam in the dispensing hole, frustrating both cat and us! Works fine with regular kibble.
