Tonight when I went to feed Malcolm and Stryker, I accidently left the screen door to the enclosure opened. I forgot to latch the door. My hands were full and I turned to put all the supplies away and discovered when I turned back around that Malcolm had stepped outside. I quickly knelt down, popped open a can of cat food, and he turned and walked back into his home. I was so surprised and relieved. This is the kitty that resembled a pinball machine when he first came here- pinging back and forth all over the place, running up the walls and looking for escape. He allowed me to stroke and pet him for quite awhile afterward. I guess the call of the can was stronger than the call of the wild.
