Bobby Corrigan is the rat master. Some call him the rat czar. To others, he is simply a rodentologist, or as NBC recently described him, “one of the nation’s leading experts on rats.” Call him what you want; he is mostly alarmed. “I travel all over the world with this animal, and the amount of complaints and feedback and questions I hear right now are all, ‘We’ve never seen rats in the city like this before,” he said. “They’re all expressing the same concern: Our rat problem is worse than ever.”
Most cities know rat woes well. Washington, D.C., for instance, has burned through countless plans to stymie its longstanding “rat problem” or “rodent crisis,” in which disease-ridden critters are not only growing in number but ballooning to the size of human infants.
