Great stuff. Well I just feed them rabbit food. The lady I got them from has lots of rats and she says they do fine on rabbit food. But I also give them some parrot food about every other day for more complete nutrition, as the rat food I saw at Wal-mart looks a lot like parrot food. Also I don't have any dandelions in my yard, all my land used to be cow fields so it's mostly clover and short grass. Anything I can use for a substitute?
