This is Gregory Gamera, The Shadow of Darkness, eating a piece of dog food that the dog "knocked out of his bowl and didn't eat. He goes in to get a snack whenever he gets hungry. He also eats cockroaches! He's a great pet - low maintenance, handy to have around the house, and he sleeps 3 months out of the year. He is 'free range' in our house. When we see him, we put him in the bathtub for a drink of water and he usually pees in there. Every now and then I find a very dried up turtle turd under someone's bed, but he doesn't eat much and poops even less," says his mistress, Mary Hestand. "Reptiles are extremely underrated as pets."
One of her daughters suggested Gregory as a name. Her son called him The Shadow of Darkness. Her husband offered up Gamera, a giant turtle and Godzilla's rival. The family decided to keep all the names.
ETA: Gregory is a female!
