Sadly, the mother didn't return - she'd probably been hit by a car, or killed by a hunter. So the lady wrapped the baby warthogs in blankets and took them into her house. Then she phoned Michele and Ian Merrifield, the cofounders of Daktari, and arranged for them to come pick the warthogs up.
At Daktari's rehabilitation center, Michele and Ian gave the warthogs the best possible care, but two of the babies died not long after arriving. They didn't expect the remaining warthog to live, based on how weak and listless he was. But with regular bottle feeds and lots of love, the last warthog - a male named Piggy - surprised everyone by surviving.
