What?....no pictures?
I think you should set up a hidden camera to capture what goes on when you leave the house. I bet Teddy goes into action before you even get out of the driveway. It probably resembles a scene from "Risky Business"....party time!!!
My last furbuddy always got into "trouble" when left home alone. I once went out the front door and snuck around onto the lanai to peek in just to see what he was doing.
Sure enough, he had started his shenanigans as soon as he heard the door lock behind me. He didn't notice when I opened the sliding door every so slowly...but the look on his face when I hollered his name was priceless! He knew he had been caught red-handed.
Oh, those were the days. I sure do miss him : -(
