Argon Chamber?

I don't know if this helps the argument any, but I would definitely go with the CO2. I've had CO2 poisoning twice, the first time was when I was much younger (therefore, much smaller), but I remember it very clearly. It was a slow leak, making the poisoning similar to the rats- but obviously on a human scale.

It caused both my brother & I to fall asleep. There wasn't any pain, obviously I didn't die either, but it was a very strange heaviness that caused us to drift off to la-la land. But, again, absolutely no pain. Nope, the pain comes when you wake up! :rolleyes: Not fun, but I can definitely attest to the fact that there was no pain in the initial process.

I've never had argon poisioning, but if they're squeaking and hyperventilating then that just doesn't sound nice all together. If it causes a struggle, then it's pretty safe to assume it causes pain- in my opinion, anyway.

sorry for high jacking this thread < but is it safe to feed a recently gassed rat to a snake ?

Becky and I are paramedics and one of the most common calls we receive is CO poisoning. We are taught how to treat it and how to recognize it very early in our training and the only symptom is sleepiness. As a matter of fact if the sleepiness is associated with chest pain or headache that's a good indicator that it's not CO.

The most common scenario we see is that the individual with the CO leak simply got sleepy and went to bed. That's why CO poisonings are so commonly fatal, because the individual feels no pain or shortness of breath just tired so they lay down to rest and never wake up. They don't call for help because they don't know anything is wrong.

What could be a more perfect form of euthanasia? JMO. :)

ScottNBecky and starstruckk - Thanks so much to both of you for sharing your first hand experience with CO2! I was always pretty confident in it but now I feel 100% sure that this is the right way to euthanize. Thanks guys! :gj:
