Why doesn simply removing feral cats from an area work to reduce their numbers and nuisance behavior?
There are many reasons why feral cat problems are rarely solved by efforts to trap and remove them. Feral cats live at a certain location because the habitat is suitable for their survival and offers food and shelter. If the cats in any one colony are removed, feral cats from surrounding colonies move in to take advantage of the newly vacated habitat and start the cycle of reproduction and nuisance behavior anew. In addition, if all the cats in a colony are not trapped, then the ones left behind tend to have more kittens that survive to adulthood due to lack of competition for resources until the colony reaches its former population level.
