What are some strange things your pet does?

My kitten likes to play with bags and play in my sons toys. She even crawls through the little holes in the toys lol. That is about the strangest thing she has done. We have only had her for a couple months so I'm sure I'll come across some other strange things. I had a cat when I was younger that would take a piece of his cat food his paw and move it into his water dish. He waited until the food got soft and then ate it. It was pretty funny to watch. \ He sometimes ate his cat food dry so I just let him do what he wanted.
