I've been trying for two weeks to catch this guy. Seems he didn't care for the marshmellows or the canned cat food. So I took some of my cat's expensive cat food and threw it in the cage. Well he must have liked it enough to venture inside to get more. I don't know what so special about this food but my cat would gorge himself on it if I let him. I only give it to him as a treat once a week.
