New England Cottontails forage alone, and groom themselves but not each other. They feed on grasses and clover in the summer, and when those are not available, turn to twigs and forbs. They maintain relatively small home ranges of less than one hectare (2.5 acres). Females are slightly larger than males, but males tend to have slightly larger home ranges. Three to eight are born in a litter, and the female nurses them for about 16 days.
