A Volunteer Map of Feral and Free-roaming Cats

Join the hundreds of other users in creating a crowdsourced geographical representation on the numbers and distribution of feral cats in your area.

The Cat Mapper Initiative

Cat Mapper is a Texas A&M University research-funded program that aims to use state-of-the-art geolocation tools to gather and share information about the growing unkown number of unowned stray and feral cats across North America. Impacts of their growing numbers are far-reaching including but not limited to the environment, wildlife, and public health. Cat Mapper seeks to populate a map with cat sightings from crowdsourced public data with details about cat health, numbers, and environmental conditions to provide a ready-made research tool for groups seeking to systematically survey free-roaming cats.


Cat Mapper makes it incredibly easy to log and report feral cats using minimal and intuitive click, tap, and drag controls, making it possible for anyone to participate!
