Rats in New York City

In 2014, the television channel Animal Planet named New York City the ``Worst Rat City in the World'', and rodentologist Bobby Corrigan called New York City the ``USA's No. 1 Pestropolis.'' Studies indicate that compared to other cities within the United States, the city is particularly well-suited for rats, taking into account such variables as human population patterns, public sanitation practices, climate, housing construction standards and other variables. Experts consider that the actual population varies, depending on climate, sanitation practices, efforts to control the population, and season.
