There are wildlife who follow civilization. Why? Because of food. There are not so many areas left that can support wild animals but most of the cities that cover them now are full of food for raccoons, coyotes, possums, foxes. (Here in Europe we don't have coyotes and possums, but we have now imported raccoons and our own red foxes who are frequently seen in cities now).

So it is an intelligent move for the wildlife to go there (better a garbage can than to wait for 5 mouses), although I am sure it's not always fun.
