Cats are cold-blooded killers, harming native wildlife populations. New research suggests the areas in D.C. where cat-wildlife conflict is most likely.

200,000 cats roam the alleys, backyards, and bedrooms of Washington, D.C., according to preliminary results from the District’s first cat census.

Scientists will soon have the first ever population count of Felis catus in the District of Columbia.

The D.C. Cat Count didn’t find many cats in Rock Creek Park, but it did spot foxes, coyotes, deer, and more.
