CET Species-Specific Euthanasia Considerations 1 — Questions and Answers
Question 1: Which euthanasia method is generally considered most appropriate for neonatal kittens and puppies under 2 weeks of age when injectable agents are not available?
- Carbon monoxide exposure
- Intracardiac injection while unconscious
- Physical methods such as cervical dislocation (Correct answer)
- Inhalant anesthetic overdose
Correct answer: Physical methods such as cervical dislocation
Physical methods like cervical dislocation are conditionally acceptable for neonates under 2 weeks because their nervous systems are immature and they lack the muscle mass needed for reliable injections.
Question 2: When euthanizing feral or fractious cats, what approach is typically recommended before administering injectable euthanasia solution?
- Administer an intramuscular sedative or anesthetic first (Correct answer)
- Use intracardiac injection directly without sedation
- Apply a squeeze cage and inject intraperitoneally
- Allow the animal to calm down naturally before injection
Correct answer: Administer an intramuscular sedative or anesthetic first
An intramuscular sedative or anesthetic (e.g., telazol or ketamine combinations) is given first to ensure safe handling and humane administration of the euthanasia solution.
Question 3: For rabbits, which euthanasia route is preferred when using pentobarbital sodium?
- Subcutaneous injection
- Intraperitoneal injection
- Intravenous injection via the marginal ear vein (Correct answer)
- Intramuscular injection
Correct answer: Intravenous injection via the marginal ear vein
The marginal ear vein provides reliable IV access in rabbits, allowing pentobarbital to act rapidly and humanely.
Question 4: Which statement is correct regarding euthanasia of reptiles?
- Reptiles lose consciousness immediately with standard mammalian doses of pentobarbital
- Reptiles may retain reflexes and cardiac activity much longer than mammals after euthanasia (Correct answer)
- CO2 is universally approved as a sole method for reptile euthanasia
- Decapitation alone is fully acceptable as a sole euthanasia method for all reptiles
Correct answer: Reptiles may retain reflexes and cardiac activity much longer than mammals after euthanasia
Reptile cardiovascular and neurological systems are highly tolerant of hypoxia, so they can retain reflexes and cardiac activity for extended periods after euthanasia drug administration.
Question 5: When euthanizing birds in a shelter setting, which method is most commonly recommended and humane?
- Cervical dislocation for all bird species regardless of size
- Intramuscular pentobarbital injection
- Intravenous or intrahepatic injection of pentobarbital (Correct answer)
- CO2 only chamber exposure
Correct answer: Intravenous or intrahepatic injection of pentobarbital
Intravenous (jugular or wing vein) or intrahepatic pentobarbital injection is recommended for birds as it provides rapid loss of consciousness.
Question 6: For large dogs over 40 kg, which intravenous access site is most commonly used for euthanasia injection?
- Cephalic vein (Correct answer)
- Saphenous vein
- Jugular vein
- Femoral vein
Correct answer: Cephalic vein
The cephalic vein on the foreleg is the standard and most accessible IV site for dogs of all sizes in a shelter euthanasia setting.
Question 7: Which species requires special consideration because CO2 is NOT considered an acceptable sole euthanasia method?
- Guinea pigs
- Rabbits (Correct answer)
- Hamsters
- Mice
Correct answer: Rabbits
Rabbits are aversive to high CO2 concentrations and may experience significant distress; CO2 is not an acceptable sole method for rabbits according to AVMA guidelines.
