Hey everybody,

So last night i euthanized some feeder rats for the first time. everything seemed to go well and the rats didn't look to be in any pain. I started off the CO2 slowly and once they became unconscious i increased the flow of CO2 into the tub. I just wanted to make sure that I did everything right and that the rats weren't in any pain. are there any signs i should be looking for that indicate the rats are in pain while being euthanized? thanks for your help!
