The gophers exhibit asocial behaviors except during the gestation and mating season. Mating is believed to be polygamous. Gestation lasts around 18 days, with each litter averaging 3 or 4 young. Females will usually have one litter per year between March and June. [9] Pocket gophers form an angled tunnel in the ground as they dig for roots to eat.
