Jack, a.k.a. "Fat Cat" has decided in recent days that he wants to be "High Altitude Cat".  Leaving the cabinet door open was my mistake.  He reluctantly came out with a minor protesting growl.  I just hope he doesn't figure out how to open the door himself.  FYI - he's staked out the top of the refrigerator as his own sniper location, thus affording him a birds eye view of the adventures of his buddy Chester.
