An animal rescue zoo in Tennessee has a new inhabitant -- a baby African crested porcupine.She's the newest family member of the Little Ponderosa Zoo and Rescue in Clinton.The little porcupine sticks close to her parents, who watch out for her, and the zoo says she's doing well."Our baby here is probably about 3, 4 weeks old. She's doing great, and the mother and father, they're really protective of her, so we try not to bother them a whole lot."It's not known whether the baby porcupine has been named yet.
