Up until recently I drove a trash truck picking up about 500 commercial or apartment dumpsters a week, at least 300 of which were actually in Hartford. There are definitely a ton of rats in the city, many the size of my wife’s cat (13-15 lbs). It did seem that the apartment buildings were worse than the restaurants/other commercial spaces, probably because they didn’t get picked up as often and pest control was not employed as liberally.
