Many feeder breeders are using the CO2 method to kill the rats they breed in order to feed their reptiles. The CO2 method can be done in two ways: pre-fill chamber and gradual fill chamber.
I've been doing some research and found that feeder breeders have decided that this is a humane method to euthanize their food. IT IS NOT!

There are many studies on going to prove that CO2 either pre-filled or gradual fill is INHUMANE.

Rats experience dyspnea at low levels of CO2 and burning of nose, mouth and eyes at higher levels of CO2.
Neonatal rats (newborns, pinkies) take longer for the CO2 to enter blood stream therefore they must be exposed longer to CO2 thus creating a longer span of suffering.

CO2 IS NOT AN ACCEPTABLE METHOD OF HOME EUTHANASIA.
 
Links to studies and other articles which supports the fact that CO2 is not an acceptable method of home euthanasia, in fact they are now saying laboratory animals should not be euthanized in this way. Again... this is pre-fill and gradual fill.
