To bad it is a rodent and not the real rat problem.
The extreme winter weather gripping New York City, where 20 people have died from the cold in just 18 days, could have an unexpected side-effect: a decrease in the rat population. Fed up with trying to combat the presence of rodents in parks, streets, and subway tunnels using countless methods, including the appointment of a rat czar, the city views this winter’s historic extreme temperatures as an effective form of natural selection.
Without the usual detritus on the sidewalks — which have been covered in snow and ice for weeks — rats are finding it difficult to feed, leading to stress that can also inhibit their reproduction. As such, not only are they hard to spot on the streets, where they used to roam freely, but this sexual inhibition promises a more merciful spring and summer for those who despise rodents.
