With that being said, when using CO2 the animals do not "go to sleep" they actually suffocate while still conscious. CO2 has a greater affinity for hemoglobin than O2 and the animals die of acidosis and hypoxia. The idea of them "going to sleep" only applies to CO exposure. I only say this because I initially mixed this up. When this was brought up to me however I had to think about it again and that individual was correct....lol a health sciences major mixing the 2 up.

I have never used co2. I do see a benefit if you have to cull many many feeders, but for me even when I had to kill even a 100 feeders the fastest and most human, not to mention the cheapest way was to simply break their necks. with rats that meant grasping their tails and a quick smack against something hard, or with rabbits holding their shoulders and "wringing their necks"
