CO2 is not painless even when the rodents do loose consciousness before suffocating. CO2 does sting the eyes and nose. And incorrect use of CO2 like using pre charged chambers, incorrect flow rate, or dry ice is inhumane and the animals do panic and feel pain. Do you know if the commercial breeders who freeze hundreds of rodents every day pre charge their chambers or care about flow rate? I really don't know, but certainly something to think about.
Good points, I'm convinced then. I didn't mean to make seem as if you weren't familiar with these CO2 procedures, I had already assumed you knew them because you mentioned your lab work. I was just posting them for OP's reference, I apologize if that came off the wrong way. I still prefer f/t only because I don't want to be responsible if my animal were to be injured because of me or if the animal were to slip up, although they are obviously extremely efficient in what they do haha
