I live in the suburbs -- nice middle income area. I am literally 1/4 mile from the mall, major shopping districts and the hospital -- just to give you an idea. Never thought I had anything other than squirrels, birds and a "few raccoons" --
Since having cameras up, and being vigilant since I have chickens, I've learnt that we have coyotes (huge eastern coyotes), fox, skunks, weasels, opossums, red-tailed hawks, eagles, owls, rat snakes, a feral dog pack that wanders, and raccoons that are huge in large numbers -- they ALL WANT TO EAT MY FLUFFY BUTTS.
I know you already saw proof of raccoons -- but I also would encourage you to put aside any thought that other predators aren't a worry because you are in an urban/suburban setting. I was shocked at how much was going on that I had no idea of just because I didn't "see them."
