This undated photo made available by Alley Cat Allies shows a cat with a "tipped" ear, indicating it has been spayed or neutered. Animal organizations are trying to cut down on the population of feral or wild cats by trapping colonies and sterilizing them. Before the cats are released, a quarter-inch of the left ear is cut off or “tipped,” considered by the ASPCA the best way to easily identify which cats have been fixed. (AP Photo/Alley Cat Allies)
