of Animal Control - In 2013, the organization published a document reviewing the treatment of feral cats in ordinances throughout the U.S. The study found that at least 240 local governments had enacted ordinances or policies supporting TNR (p. 4), a ten-fold increase from ten years earlier (p. 11). Scientific study of neuter status of U.S. pet cats - In 2009, Alley Cat Allies published Population Characteristics and Neuter Status of Cats Living in Households in the United States in the Journal of the American Veterinary Medical Association. "Findings suggested that a high percentage (80.0%) of cats living in households in the United States were neutered and that annual family income was the strongest predictor of whether cats in the household were neutered." U.S. Public Opinion on Humane Treatment of Stray Cats – In 2007, Alley Cat Allies published a document interpreting the results of a survey the organization hired Harris Interactive to conduct. The survey found that 81% of Americans consider it more humane to leave a cat outside where the cat is, rather than have the cat caught and "put down."
