I recently noticed that Katie has giant, round cheeks. It dawned on me that she probably has very muscular jaws from chewing on two or three frozen, stuffed Kongs each day. Just look at the ripples in her cheeck below. This girl loves her Kongs. I have started stuffing them with kibble and oatmeal before freezing them. The oatmeal glues it all together and makes for a very stubborn Kong for a very efficient Kong destroyer.
