Some of these methods, while creative, funny, and macho, are, nonetheless, illegal, and could land you a hefty fine if reported to the police, or, better yet, if you're dumb enough to post a video about them. Be careful, guys.
In a neighboring county, a work acquaintance was arrested for shooting a cat with a paintball gun, and ended up with a $750.00 fine (cruelty to animals), court fees, vet costs (to remove the paint and treat the cat's bruising) and the paintball gun (not cheap) was confiscated.
Seems it was his neighbors cat, and the neighbor was unimpressed with his skills.
It makes for a wonderfully funny story, but an expensive one, and I think the cat had the last laugh.
Just be careful, and use your head.
