Not to start a debate but how is wacking them against the wall be less humane that CO2? When they're slammed against a wall, table etc. its instant death, unless you give a little girly swing (no offense). They're dead before they knew what hit them and it is much faster! CO2 on the other hand is something that doesn't kill them right away. It's "painless", but it does take some time! Ever have your breath cutoff by being choked out or the likes? I have when we were doing combatives in the army during training and it doesn't feel much good at all. I'd imagine this is what it feels like to be put down by CO2. You really do freak out alot, and then you start to "lose it" towards what you think, and your awareness. I do believe "wacking" the prey Item against a wall or something of the likes is as humane if not more so than CO2. Myself, I'd much rather go down instantly and pain free, than suffocating no matter how quick it is.Originally Posted by sweety314
