How Are Rats Euthanized?
WouterRats can be euthanized in a number of ways. Usually, the process involves using carbon dioxide (CO2), which is a central nervous system depressant. The gas makes the rat unconscious without suffocation. If the CO2 is too high, the rat may yawn to get rid of the excess. If this happens, extra vinegar and baking soda can be added to the aquarium.
Rats and mice do not exhibit a strong sensitivity to pain. Often, the methods of euthanasia are considered acceptable if the animal is unconscious. However, there are risks to the operator and other bystanders. Additionally, the literature on euthanasia is incomplete. Various factors, including species differences, may influence how animals experience pain.
The optimal method of euthanasia depends on a number of factors, including the scientific goals of the study and the ethical considerations of the personnel. Regardless of the method, however, the goal is to minimize the animal’s suffering. Various considerations must be taken into account, including the veterinary staff’s training, the safety of the rodents, and the guidelines for euthanasia of rodents.
One method of euthanasia is through an intracardiac injection. The rat is put to sleep with this injection. This isn’t the most humane method, however, and is illegal in California. It is only safe when the rat is highly sedated or anesthetized, and should not be used on an awake rat. Furthermore, locating the heart may be difficult, and the injection may accidentally enter the lungs.
