Awesome, i'll give this a shot tonight. My fioance is pissed at me because i freeze the rats and one managed to get out of the box and loose in the freezer for about three days, chewing it's way through hot pockets... stupid rat.
Anyway, can this also be used to anestisize (or however it's spelled) the rats for examination (i.e. sick breeders) or only for euthanization?
CO2 is not an anesthesia and can never be used to anesthetize a rat. Only a veterinarian can anesthetize an animal and by using the appropriate drug (anesthesia). Good luck.
