We euthanize our animals quickly and humanely with carbon dioxide (CO2), as recommended by the American Veterinary Medical Association panel on euthanasia, then tuck their legs and tails neatly underneath their body and freeze them immediately. When completely frozen, they are counted into re-closable freezer bags and stored properly to prevent freezer burn. CO2 ensures a humane, quick and painless death for the animals and leaves no harmful residual chemicals that may harm the animal ingesting the prey item.
