Yup.
I remember walking in the evening in a nice rural college town, and I saw the biggest rat I've ever seen, just waddling past a house porch - the thing was larger than some good size cats, and was unmistakably a rat when it got in the good lighting.
I was of course just stunned thinking WTF!??!, then walked on, and it turned out that that house was adjacent to the back of a grocery store lot, and the corner where the dumpsters were, only a few dozen yards away in a straight line... Well-stocked dumpsters clearly make for fat & happy rats!
