Strange things your pet is attracted to

My dog absolutely loves to play with plastic pop bottles. If she sees you drinking a pop she'll come over and try to knock it out of your hand to play with it. She gets a kick out of pouncing on them because they'll roll away and then she'll pounce again. It's so cute. It's pretty much the only thing I've ever been able to get her to play with. I've bought her plenty of dog toys throughout the years and she's never very interested in them.
