Pets behaving badly?

I once had a cat, Conrad, who loved to chew up my contact lens case, while my contacts were in there. He did this twice before I learned to put the case away in a drawer. When I was a kid, our poodle Fluffy had a litter of puppies in my bed. Under the sheets, by my feet, while I was sleeping. I had a very rude awakening!
