Max (my avatar picture) and my cat Nip did a number on my house the first time I left them alone, together. As I drove up to the garage, the first thing I saw was what looked like snow in the dog pen. As I entered the basement, I saw Max had "discovered" the 12-roll package of TP waiting to be taken up to the bathroom -- hence "snow" everywhere.
Entering the kitchen, I discovered a now-empty (plastic) jar of dog treats that had been purchased along with the TP. The living room: apparently one of my down pillows had been "bad" so Max had attacked it and then shook it to death: feathers strewn from pillar to post. Then I heard a thump, thump, thump. Nip had caught a live chipmunk and put it in the bathtub so she could watch it run around in circles! Wish I had had a video!
