UPDATE: Chimpanzee Stevie is now 10 weeks old, 6lbs. and thriving at Zoo Knoxville. She is beginning to crawl, working on sitting up and getting her first tooth any day now! A team of expert caregivers are still caring for her around the clock until she reaches a more independent stage to reunite with the troop. She spends face time with the other chimpanzees daily at Chimp Ridge.
