Mice seem tougher to breed and do smell quite a bit stronger than rats. For one snake that happily eats f/t I'd say it might not be worth your while but if you are wanting to breed mice and don't mind humanely euthanizing and freezing them properly then by all means give it a shot.

If you have access to a Pet Supplies Plus, Petland or PetCo they almost always have a nice selection of frozen mice/rats. They may not be the cheapest place but with no shipping to pay and only one snake to feed it's a pretty reasonable weekly feed bill.
