Ratting Out NYC

Washington DC recently launched a campaign claiming that NYC has rats the size of house cats because they aren't strict about food and drinks in the subway. New York subway tunnels might have a lot of rats, but I've never heard of anyone say they've seen a rat inside an actual subway car (or even seen a rat the size of a house cat). I would imagine food on the subways is a small contributor to the rat problem. That's an awfully slippery slope DC.
