The crested porcupine at the Great Bend Brit Spaugh Zoo may be going on a diet, Zoo Supervisor/Curator Sara Hamlin said Wednesday. “He is kind of a chunky monkey.”Local veterinarians Dr. Mike Malone and Dr. Jackie Corbett performed a physical exam on the animal. These routine procedures typically occur on Wednesdays and the public can watch through a window located in the zoo’s headquarters, the Raptor Center.Hamlin said the zoo has acquired a second crested porcupine, also a male, and she hopes the two will share exhibit space.
