We eat lean meats, so if it's beef, pork or chicken I will cut some off and cook it in another pan. When I buy sirloin or beef round they go nuts. They love the stuff. I will cook it with a few greens or chop up a piece of potato or sweet potato and cook them until just about soft. they get raw veggies and yougurt for calcium. They have a very varied diet and I always have zoo keeper secret just in case one of them decides to be a brat and not eat their veggies that night.
