I do the whack a rat thing for mine. I am now thinking of buying frozen but I have a hang up about the CO2 thing. I cannot comprehend how gassing is less painful than a skilled one time whack. I have read threads about this same topic over and over and although I agree that it is best for the consumer, I can't seem to bring myself to the thought process of it being more humane for the prey. If someone could enlighten me on the physiological process that occurs in the prey being I might be able to let go of my hangups. A later post stated that the CO2 process happens quickly, in 30 or a few more seconds. Although I don't like to whack 'em or slam 'em, a second of actually pain/fear seems to me the way to go. I cannot imagine that an animal whose brain is basically crushed could feel pain. I think the adrenaline and instantaneous trauma would reroute all function away from sensory perception. At worst you get a seizure, but from what I think about seizing is that it isn't painful, but disorienting.

Please advise if you know otherwise, like I said, I just don't understand.
