I feed hog food from the local feed supply store. It runs around 10.99 for 50lbs. I have not had any problems with it. I also mix it with dog food, though you don't have to. I also feed them table scraps once a week for variety. My rat rack is built with concrete mixing tubs from Lowes. They are around $5.00 a tub. Here are some pictures!



Good luck!
