it is a toss for me. i like rats personally, however i do have allergies to them. but will deal with it when needed. i mainly order F/T's, but will breed for hatchlings if i got the time and space to do so until i get them switched to F/T's. after that, i do not have any local hook ups for anything thing smaller than adult mice, and small/medium rats, and $5 for an adult mouse is crazy!!!!!.
