Okay...there is a lady dubbed "The Rat Lady" her real name is Debbie Ducomun (not sure of the spelling) but she is awesome! She has a site and a diet she formulated for her rats. When I had my rats I made it for them. It has things in it like soy nuts, rice cereal, puffed wheat cereal, dehydrated fruit, oats, etc! I'll try to find the website for you. Hehehe.
