Removing cats from an area by killing or relocating them is not only cruel, it's pointless. Scientific research from animal control prove that catch and kill doesn't clear an area of cats. Each time a cat is removed, a new one will appear, or a kitten will survive through a natural phenomenon known as the "vacuum effect". This creates an endless cycle of trapping and killing.
TNR is the only proven, effective, and humane way to control the cat population. Neutered cats are returned to live out their natural lives. The breeding cycle stops - no more fighting, spraying, yowling, roaming, and producing. The cat population stabilizes and declines over time, reducing the surplus of cats to the shelter and lowering euthanasia rates.
