I’ve caught hundreds of raccoons in DP traps and have never had a raccoon chew off his paws. Trapping raccoons requires you to check the traps early in the morning around sunrise just for this reason.
There are plenty of ways to protect your ducks chickens or whatever you have without trapping...
Use a dp trap and smack em on the head with a pipe. Simple. Reset trap in 3 seconds without transporting a heavy raccoon in a cage to water. Dp traps work far better than a cage and are cheaper.
Why don’t you get a gun and shoot the raccoons since you video tape them all the time?
Drowning is pretty piss poor imo. Shooting or a hard hit on the head with a heavy pipe, bat etc.. will put them down quickly.
Seems to me people drown animals because they can’t actually kill them themselves.
