Hk45USP, leave it to humans to mess up nature. Pets get dumped back into the wild generally don't have many natural enemies so there is nothing to stop them from multiplying in large numbers. They upset the balance of the local ecosystem by depleting resources that would otherwise be used by the "native" wildlife, to include predators. They also carry disease and spread it to other species. By disposing of these animals, you are preforming a necessary service. I have pretty vast experience with feral dogs and cats, even if they could be caught, most could never be domesticated from their wild state. The only recourse is to humanely destroy them and I can think of no better way than a bullet through the brainpan. They never know what hit them.

Looks like I won't be eating cereal for awhile.
