I live in a smalll town we have two small pet stores.. One is a group of 18 year old girls who are selling hoppers mice as full grown $3 each.. The other is a family owned pet been open for years they take care of their animals for the most part well. Both want $6 dollars for small rat.. I checked the notice board on the walls and found a local girl who breeds them for herself and her bother both have multisnakes.. She cost me 1 per large full grown mouse.. i got lucky..
