It is estimated that tens of millions of feral and stray cats freely roam the United States and rapidly breed. Lack of action and ineffective approaches have resulted in a serious population problem.

Trap-Neuter-Return (TNR) is the only method proven to be humane and effective in controlling free-roaming cat population growth.
