In our search for decent lab chow in a 50 mile radius, I found a company that can order the Mazuri 6F, but also carries the Purina 5008 for $26.50 for a 50 lb bag.
It seems to compare decently to the 6F, except that its protein is higher, and its listed for hamsters as well as mice and rats. Has anybody used the 5008?
Currently we've been using dog food, and a mix similar to Becky's mix without the lab blocks, but I want to find a food that doesn't require so much supplementation for as we grow.
