According to a study released today by the Straphangers Campaign, rats have been spotted at 13 percent of underground subway platforms in New York City. Furthermore, the study revealed that the most—a staggering 21 percent—were seen in the Bronx.

Rodents were seen at 15 percent of Brooklyn and 10 percent of Manhattan platforms, respectively. According to Bronx passengers, the prevalence of rats is the result of commuters littering. Also, these rats are huge. "There are a lot of them and they are big," Khadija Harrison told the New York Daily News.

Oddly enough, there's an upside to this rodent problem: that 13 percent citywide figure is a three percent drop over last year. It's one small, unnoticable step for New York City.
