When I used to live with my grandparents, we had an old fashioned stove, you know the round shouldered old fashioned ones with the heavy oven doors. One Thanksgiving, I went into the kitchen and noticed that the stove door was open, the enormous (and heavy) roaster pan was on the floor, the top removed and half the turkey was gone. And my very well fed cat was hovering over the remains. I was so perversely proud that he figured out how to do this - I mean the cat only weighed 12 lbs and the turkey itself was twice his heft, not to mention the door and baster pan - that I couldn't really be mad at him. But we ate meatloaf that Thanksgiving. And we always put a REAL heavy chair next to the oven door from then on in.
Oh my goodness. To tell you the truth, I would forgive him as well Nothing beats the real aroma of turkey and having to find your way through to get to it.
I don't know about a horror story, but one time one of our cats climbed up the side of our house about 10 feet. A dog was chasing it.
I got a story I got from a coworker. A few years ago this coworker was taking his sisters rabbit to the vet, it was in a cage but escaped while he was driving to the vet. It decided to hide under the brake pedal, and my coworker didn't notice this. While he was driving someone cut him off and he had to slam on the brakes. He ended up crushing the rabbits skull into the floor board.
Yeah, a friend of mine got drunk and sat down on his pet kitten, didn't know about it till he woke up the next morning.
