This is not directed at anyone in particular, just my opinion on all of this, in general.
Each of us is responsible for the actions of our cats, dogs, iguanas, and children. It is our responsibility to ensure that none of these has the opportunity, through our own negligence or lack of sufficient oversight, to damage, defile, or otherwise encroach on someone else's property or posessions. To me, it's simply a matter of being a responsible, respectful, considerate, and civilized neighbor.
For people that let their pets run lose. . . . Do you really want to risk losing your pet to an irrate neighbor? It only takes one. Years ago, the lady down the street poisoned one of my cats and killed it, because it was trashing her garden. Who's fault was that? Mine! . . for being irresponsible and letting the cat have the run of the neighborhood. Unfortunately, I didn't "get it" at the time and I had to learn a hard lesson.
For people that have kids . . . . I could speak volumes about this, but I'll just say that kids that are taught personal responsibility and to respect other people's property will not end up being the ones that ding other people's car doors and cause other property damage.
