Can I catch beaver in them? If so, what lure or bait would i use? Also, I watched the DVD "Practical Fur Handling", and the guy said you can kill skunks really fast by attaching a hypodermic needle filled with acetone to a stick, then injecting them, so they won't spray. Will this work for all animals in a cage trap? It just seems hard to pop them in the head with a 22 in the cage. Maybe a stupid question, but I would like to know what you all do to kill them in cage traps. I guess I could tie a rope to it and chuck it all in water to drown them.
