CO2 for feeder euthenasia
So I've been looking more into feeder euthanasia, how humane it is, and if there could be better ways to do this other than CO2 that are, similarly, less hands on.
The main problem I've read about with CO2 is that CO2 actually causes pain and suffering as the excess amount of CO2 is what causes feelings of suffocation, not the loss of oxygen. There have been studies done as far back as in the 2000s but more commonly started in 2005. All of which say its probably painful no matter how you do it (with CO2) , but that the only better way is the hands on version of killing the animal (neck and tail trick).
Many people do not have the heart for that and opt for CO2, but if that is still painful then what else can we do? I'm sure more research can and will be done on this topic but does anyone have any current ideas or suggestions on the most effective, least hands on, and least painful way to euthanize?
I have one idea, but I'm not entirely sure if it would work as Ive not done any research on it (yet). As most studies have shown its not the loss of oxygen that hurts but the inability to exhale CO2. This bring me to the idea that *maybe* if there was a way to remove oxygen without adding anything then the death would be more peaceful? instead of pumping in painful CO2 simply removing all oxygen slowly.
I am hoping for a friendly open-minded discussion about this, please don't be super stubborn and unwilling to learn as this is new ideas. Also feel free to correct why my idea may be or is proven to be wrong as well! Look into CO2 and why it can cause pain if you haven't heard of this before. it is interesting and mostly applies to humans as well.
