switching from f/t to live?

[Pythonfriend]

There really is no pretty way to prekill rodents. Building a little gas chamber is the best method...Co2 canister, tubing, and a rubbermaid container will do it.

CO2 is not the right gas to kill rhodents, because mammals can detect any rise of CO2 levels in the blood and this will cause cramps, panic, convulsions, pain. Its quite quick, but not nice. this CO2 buildup is what makes death by drowning or lung failure or asphyxiation so terrible.

Go for helium or any other noble gas or just nitrogen, takes longer but the mammals just fall asleep and realize nothing, because they can keep exhaling the CO2. Or, the best, nitrous oxide, painless and super fast. on youtube you can see crazy people doing it for fun.

but, really, STAY AWAY from CO2, of all available choices, of all that you can easily get in a pressurized can, its about the worst choice you can make. except for maybe ammonia or chlorine. Spread the word.
