When I lived in Mississauga, ONT, there were signs stating to get out of the park after 11pm as the coyotes may attack. I always laughed when I saw the sign at 1am when I use to walk Cyrus the Staffy. They'll only go after the smaller animals, not a big dog or a human (unless they are ill, but that doesn't count IMO)... THere are also a lot of people who feed them in the winter as they keep the rodent populations WAY down in the summer.... but sadly there is an illness going around right now that killed a lot of them, coons, & skunks

I'm really not against them living in cities, as we need them & they are usually anti social, well except the semi tame ones that stupid people create/feed by hand... idiots...
