I knew a guy in the 70's who was a real nature freak and adopted an abandoned baby raccoon. Things went swimmingly until one day when the coon was about 6 months old and the guy left him inside while at work. Let me just say that his Large Advents looked like they had encountered the MOAB. Never realized until then just how much thread was in a speaker grill, how much paper in a cone, or how much wire in a cabinet.
But the coon, he was just fine!
