I have been buying frozen mice from from Petco but would like to switch to ordering from a repeatable place. They have very basic sizing of mice and rats and the quality occasionally looks questionable. My female BP is coming up to 350 grams and I would like to step her up from adult mice to weaned rats. Does anyone know of a rodent company that ships in lower quantities? I looked into Rodent Pro but I don’t need to buy 25 weaned rats at once. Any suggestions?
