A simple but great idea for feeding rabbits! However a tip to everyone - pellets are not ideal for feeding house rabbits!!! Most pellets even those bought a stores such as pet smart are for feeder rabbits! They often make your own rabbits obese and ill. Hay is a much better and cheaper solution!
@ Bruce: I want this!!! Wasted feed drives me NUTS. After much research, contemplating dozens of designs and several iterations of my own, I am now happy with my feeder. There are no longer piles of wasted grain on the floor. Wa-hooo! Mission accomplished. I made my feeder, and you can make one too, for around $12.00 and in about 20 minutes.
