I do not know if I have introduced our mice before, but if I haven't here they are!
The mainly black one is new just a few days ago, he is a male to breed from, he is actually a fawn, white and black tri colour. The two girls are mainly fawn with some white. The offspring have a nice life here until they are large enough to be snake food! I do not feed them live to the snake though as that is not very ethical, we euthanise them and freeze them to be used as needed.
