to keep your cats inside if they are pets. i don't see the point in having a cat if you let it run outside. outside cats are prone to getting run over or in fights with other animals. they also kill hundreds of songbirds- because that's what they do- they hunt. keep your cat inside.
on a related note- many serial killers get their start on small animals. just sayin'.... this kid does have a bit of the charming bundy in his eyes.
