I find dead ones just outside (unit block of Gallatin St, all the time (killed by the herd of alley cats that also are running rampant in the alleys here and use my yard and the neighbors' planters as a litter box). Last month, I had one in my house! Don't know if it came up through the sewer or in through the garage but it was horrible. Bought a snap rat trap and got it on the first try.
