Tens of millions of feral cats roam the U.S.

Cat overpopulation and the wild nature of feral cat forces shelters to euthanize over a million healthy feral cats each year.

Trap-Neuter-Return (TNR) — trapping cats so they can be taken to a clinic, spaying or neutering them, and returning them where they were found — is the most effective and humane way to control the feral cat population.

Project Nala is a collaboration between Carnegie Mellon University and the Animal Rescue League Shelter and Wildlife Center. The Animal Rescue League provides help for those in the Pittsburgh area who maintain or need feral cats trapped.
