We set a live trap and caught several raccoons, a opposum and a kitten. We did not kill any of them. We took the critters (not the kitten) several miles away to a large park/lake/creek area and let them go, with permission from the county. Sorry, cannot imagine drowing any animal. If you are going to kill it, at least do not make the animal suffer. Shoot it, but if you plan on killing it, you should plan on eating it or giving it to someone who will. Have not had any problems since. ;*}
