Breeding Mediterranean Lemmings
It has been suggested for breeding that Mediterranean Lemmings benefit from efforts made to mimic the summer months. This can be done by using a bright light source above the vivarium for 12-24 hours a day and by ensuring an abundance of leafy greens. The additional light and food should help trigger their normal summer behaviour.
Mediterranean Lemmings reach sexual maturity at 5 weeks and have a gestation period of 18-23 days. Litters range from 4-8 and the young are weaned at 4 weeks and given the early sexual maturity should be separated out at this time.
