So, I need to jump in here for a minute to ask about gram size. The Mouse Factory lists their small rats at 55g, their medium rats at 80g, and their large rats at 122g. In comparison, the American Rodent Supply lists their small rats at 50-75g, small+ at 75-95g and medium rats at 100-195g.
When you are all saying small, or maybe medium for the larger ladies, what gram size are you referring to?
