Parasites of the northern pygmy mouse include the intestinal nematode Pterygodermatites baiomydis.[3] The average size of an adult male is approximately 7.5 grams (0.26 oz), while adult females can weigh up to 9.4 grams (0.33 oz).[4]

Reproduction

The pygmy mouse has litters of 1 to 5 pups, with an average of 3. The gestation time for pregnant females is less than 20 days. Unlike many other rodents, father pygmy mice will care for offspring, and groom and huddle over young.[4]

Communication

In captivity, these mice will sometimes produce a 'squeal', and use a posture similar to singing mice.[4]
