Hmmm...I usually mix the cheerios in with their seed diet. There is about 8 pounds of seed mix in a tin drum. I mix about 3-4 cups of cheerios in. As far as I know, they can have cherrios as much as they want...it doesn't hurt my babies.

I give my rats Innvoa dry dog food, and there is about 4-6 cups mixed in the seed. They also get IAMS wet dog food about once every two weeks or so...sometimes more.

Keep in mind I have 8 "piggys", that is why there is so much food.
