Look up the definition of the word pet. Chances are if you have a pet, you control it & it doesn't roam free. Also, most pets do get out or loose on occasion but generally have some sort of collar on. Even with a collar if it is roaming free, it's probably a nuisance to someone else. Cats & dogs kill for sport, not just to eat. They dig holes, damage property, [beeep] all over the place. They even cause general anxiety in people that are afraid of them. I have a sister that was attacked by a standard poodle almost 40 years ago & is terrified of dogs. This isn't a bully dog breed or some media hyped breed. My opinion, it's irrational but not my fear; I didn't get attacked. Long story short, if it's running loose it won't be for long. I know my neighbors & they're pets, which do get out on occasion. They don't get shot, although I will fire to run them off. Just for reference, I have both cats & dogs as pets.
