I need to know the best way to make feed last a long time. I was putting a new door on the cage today, and stepped on a nail. I can't walk too good. I need to be able to make the feed las as long as possible so I don't have to limp out there as much. Plus I need to save some money on the feed bill. Those little things spill so much food I could stand by the cage and catch it as it falls.
