Chicago takes 'rat capital' title over NYC. See story here. http://www.fox32chicago.com/news/chicago-takes-rat-capital-title-over-nyc#/
New York is not the big cheese when it comes to rodents. The Second City has been dubbed the "rat capital" of America according to apartment search service RentHop, which said Chicago had the highest amount of rat-related complaints of four major U.S. cities. Data compiled by the website showed that there were nearly 51,000 rat-related complaints in 2017, Chicago had the highest amount of rat-related complaints of four major U.S. cities.
Many buildings and the garbage in them make Chicago an excellent place for rats to survive. Rats can carry many forms of virus and disease. This obviously is one title Chicago is not too happy about.
