“Some people have a rare disorder — Munchausen’s — in which they deliberately cause illness in others, and then use the illness to get sympathy and medical attention. Most cases involve mothers who hurt their own children, but a new report shows that people with this illness may also hurt their pets.” Reuters Health

[Addendum: Hal is of course completely correct to note that Munchausen’s Syndrome is the name of the condition where you induce illness in yourself for the gratification the medical attention provides. It is “Munchausen’s by proxy” when you do it via your child or your pet.]
