They are instinct driven and little care is given after the initial post-natal period. The offspring usually mature rapidly and reproduce early. One or, at most, a very few offspring are born. They receive care for an extended period of time, usually years. They mature slowly, learning a great deal from their mother.
Most rodents are quite social, living in large groups with elaborate interactive behaviors.
The prairie dog is a prime example. Prairie dog towns can be hundreds of yards on a side and home to hundreds of the little ground squirrels. Solitary life-styles are restricted to species living in arid grasslands and deserts. Having very acute senses, rodents communicate by sight, sound and smell. They make considerable use of vocalizations, some of which are above the human hearing range.
