Suebee's is definitely a good and popular diet and very trusted among the rat community.
A very excellent food is Oxbow Regal Rat Food, it's high quality with NO corn! They also just changed the formula to make it more palatable so there is a better chance your rats will like it as many rats often refuse to eat it ( Although I never experienced this with any of my 7 boys )
