That’s exactly what the environmentalist wackos say. Check out the list of diseases (and severity of same) transmitted by cats to people. Got nothing against cats, but they stay outside around here.

Well, I’m not an environmentalist wacko, and if any e.w. has ever said the above, which is what I said, I’d really love to see the sources.

Diseases that cats spread to humans fall into two main groups, namely parasitic infestations and bacterial or viral infections. There are very few diseases that can spread from cats to humans. The only two that have potentially serious/fatal consequences to normally healthy people are toxoplasmosis and rabies. Cat faeces can be the source of many infections and should not be handled without gloves. Washing of hands after handling faeces is essential. All bite and scratch marks should be washed immediately with hot water and disinfectant or soap.
