They are fitter and healthier than any other lemmings I have seen, mainly because they have adapted (well) to being kept as domestic pets but also because breeder's husbandry has been refined to better suit their needs.
Please feel free to contact me for any information on these wonderful little creatures - I often have babies available in same sex pairs or unrelated pairs and trios. They are expensive but this is to put "fad-ists" off
