CO2 for feeder euthenasia

[craigafrechette]

I'm not 100% sure I'm reading the original question right.

It sounds to me that you're proposing simply cutting off their oxygen and letting them suffocate?

I'm not too sure how painful the CO2 is, but I'm guessing if it was up to me I'd want it to be as quick as possible.

Suffocating the animal doesn't seem any more humane than freezing them to me.

But again, I'm not sure if I'm reading your question right.
