I'd sure as shit not want my kids (I only have cats) going to a school (or pet sitter) where other kids (cats) were potentially infected with FIV (cat AIDS) or FLV (cat leukemia). Not all kids (cats) can get vaccines (don't exist for my examples), but still - meet some common fucking health requirements. Herd immunity is necessary for those allergic to egg or whatever it is that physically prevents them from being able to be vaccinated (fuck you Jenny McCarthy in assisting in several deaths due to people not immunizing when they could have).
