If you notice in the study it says stuff about a little boy getting sick from sleeping with a FLEA INFESTED cat... uh, who lets their kids sleep with a cat infested with fleas?
I'll take my chances. Everything in this world is dangerous in one way or the other. Our family has slept with our pets in our bed our whole lives, including my GSD and Golden Retriever, and many other dogs in our family. No problems here.
The media tends to be over dramatic with everything they report anyways
