Mauling isn't restricted to big dogs.

It can happen with toy sized dog as well. And it can happen with your cat too.

There was a story I heard long ago of a new born babies lip and mouth area being mauled by a cat. Baby had just nursed and had baby formula on his face. Cat came by licked the formula and got carried away. This was told to me by my father, an MD. (I think the baby was one of his patients)

You can't let your guard down even with your family pet.

Too many sad stories... Truly tragic. The 17 YO will never forgive herself.
