Female warthogs have up to eight young at a time, though they usually only have two or three, after a gestation period of around six months. Baby warthogs are called piglets.
Female warthogs, called sows, are social animals and live in groups called sounders, which can contain up to 40 members, according to the San Diego Zoo. Females groom each other and huddle together at night for warmth. Adult males aren't as social and can be territorial. Often, they live alone.
In general, warthogs forage during daybreak and the twilight hours. If they live in a dangerous area, they forage at night.
Warthogs are often perceived as vicious animals that attack and eat prey. Actually, warthogs are herbivores, which means they eat vegetation, according to ADW. A warthog's diet includes roots, berries, bark, bulbs, grass and plants. During times of scarcity, warthogs may eat meat, but they don't hunt. They munch on dead animals, worms or bugs they find as they forage.
