Sam Miller, media relations manager of the Humane Rescue Alliance (HRA), pets a cat at an HRA animal shelter in Washington, DC, on October 15, 2021. - A striped feline leaps from a rock under the shade of a tree on a late October morning. As its front paws touch the ground, the whiskered creature looks up, eyes darting left. A wildlife camera clicks and captures the scene. It's a cat and the location isn't a remote rainforest, but the capital of the United States. The photo is part of the DC Cat Count, a first of its kind, three-year effort by animal welfare advocates, conservationists and scientists to enumerate every Felis catus in Washington.

Animal welfare advocates, conservationists and scientists have carried out a three-year effort to count every cat in the US capital and provide an accurate estimate of the size of Washington’s indoor, outdoor and shelter population, as well as the health of the city’s cats.
