Even in this town that might be frowned on... But I've shot a lot of domestic cats. I was only three miles out of town in SD and I'd see cars stop at the top of my 1/4 mile long driveway and then turn around and go back to town, and I know they were dropping off cats. I had nine show up one week. The closest county shelter was 25 miles away so that wasn't feasible, even if I could have trapped them and done several at a time. Besides, I know enough about shelters that I know they would have been euthanized anyhow. Personally, I think a quick, surprise death was more humane than being trapped, caged, transported, and then caged again until they were killed with gas.
