Gosh Karen, that is scary! Mack has done it a time or two, but he is just bossy and is trying to escape when he gets trapped in the garage. Thank goodness the garage door has been down most of the times it has happened! Butter disappeared for almost 24 hours one time and I was so worried and when I went to ask my neighbor if he had seen him, I heard Butter crying nearby. Turned out he was locked in the neighbor's garage after being nosy and investigating when the door was open.
