Author's Note: How a Flea Circus Works

Fleas can jump about 150 times their own height. They'll put that incredible jumping ability to work as they pounce on anything resembling food. That might be your cat or your dog. And if don't treat your pets regularly to ward off fleas, the little buggers might wind up sucking on your blood, too. These are the sorts of thoughts that ran through my head as I sat in a good friend's home, watching fleas flickering wildly through the family dog's fur. I had plans that night to crash on their couch; after witnessing the dog's unhappy infestation I decided to make other plans very, very quickly.
