Stressed Baboon and Son: "A baboon mother's `over-zealous' grooming of her baby to baldness at a Devon zoo is a sign of stress, says an animal rights group. Reggie the hamadryas baboon has had his hair licked and plucked off by his mother at Paignton Zoo. Now PETA has called on the zoo to stop hamadryas baboon breeding. The zoo rejected PETA's call and said the baboons showed no signs of stress."
