That warning is based on the case of a German women who repeatedly battled the same strain of the drug resistant superbug MRSA. Health experts finally examined the woman's three cats and one turned out to have the same strain. According to a report in the New England Journal of Medicine, once the cat was treated, the women's infections cleared up.
Researchers already know that people can pick up such infections from dogs. They say its a good idea to regularly wash up after handling all pets.
