Here is a real threat-
Although anti-wolf people try to scare us with the seldom caught Hydatid disease which is almost entirely spread, by dogs, fox, and coyotes, here is the latest on a very important threat from scat — domestic cat scat — toxoplasmosis gondii.
I have mentioned T. gondii a number of times. The latest research (from the Journal of Wildlife Diseases) show cats sicken many kinds of small wildlife, as well as 25 per cent !! of the human race. Cats Pass Disease to Wildlife, Even in Remote Areas. Science Daily.
One of the most creepy things about T. gondii is that directs the brain of the host animal (what about people?) in some cases. For example, it makes rats and mice love the smell of cat.

On the basis of sheer statistics, a number of folks reading this post are infected with this parasite.
