The most common preferred method put forth by animal control organizations for control of cats has traditionally been to capture and euthanize feral/unowned cats. Others, who refer to this means of control as the ``trap and kill'' method, consider it inhumane and objectionable on several fronts. A major factor has been that it has been shown that as soon as a cat is removed, a new one will move in to take over the food source[Ref1]. Additionally, unless the cat is making an unusual pest out of itself, why should a wild animal be euthanized simply for not having a human address?

What is the SPCA's policy on feral cats now, does anyone know? It used to be that they all were killed right away.
