I live in the state of California and for the past 6 months my neighborhood has been seeing TONS of cats around. 6 months ago it was 3 cats now it's about8-10. They don't belong to anybody as they just hang out at this foreclosed house opposite side of my backyard. They always get into my garbage and tearwholes in the bags and cause big messes. If one is in my back yard, am I allowed to shoot it with a paintball gun?
