Why doesn removing feral cats from an area work?
Animal control’s traditional approach for feral cats—catching and killing—is endless and cruel, and it does not keep an area free of cats. Cats choose to reside in a location for two reasons: there is a food source (intended or not) and shelter. Because of a phenomenon called the vacuum effect, when cats are removed from a location, survivors of the catch and kill effort and new cats who have moved in breed to capacity. Cats have been living outside alongside people for 10,000 years—a fact that cannot be changed. Learn more about the vacuum effect.
