"Reggie Rat is better than most comercial pet food on the market, but that is not saying much. I used it for a couple of weeks with my rats, and when I switched to a home made mix and high quality lab blocks, their coats became shinier and softer.
Reggie Rat doesn't use soy (very good for rats) as a major ingredient, but corn is one.
I would recomend either ordering a high quality lab block, or using a home made mix (there are several)."
