The Caucasian snow vole is a terrestrial species, developing outside of water bodies, reproducing through conventional sexual means with fertilization and without alternating generations. Embryonic development lasts 1 month 3 weeks; females give birth to from 2 to 5 offspring, with an interbirth interval of from 1 month 1 week to 1 month 3 weeks. Live young are born on land, sighted, and covered in fur, and the mother feeds them milk for several weeks. Eggs, larvae, or young can develop in a terrestrial nest located on or near the ground, lying directly on the soil surface without shelter. The nest is situated directly on the ground surface, and only the mother exhibits parental care. Females give birth multiple times during the warm season, and sexual maturity occurs from 8 months to 1 year.
