These little guys are so difficult to capture... they have these little nervous "outburst" runs. Just as you think you have them, the hurry off closer to mom. Just the cutest thing I've ever seen!
The typical gestation period is five or six months. When they are about to give birth, sows temporarily leave their families to farrow in a separate hole. The litter is two to eight piglets, with two to four typical. The sow will stay in the hole for several weeks nursing her piglets. Warthogs have been observed to engage in allosucking. Sows will nurse foster piglets if they lose their own litter, making them cooperative breeders. Allosucking does not seem to be a case of mistaken identity or milk theft and may be a sign of kin altruism. Piglets begin grazing at about two to three weeks and are weaned by six months. Warthogs are considered a "follower" species as the young are kept nearby at all times and do not hide.
