My $300 alpaca got stomach cancer. When we decided against the several thousand dollars for surgery, he starved nearly to death. When hecouldn’t get up anymore, I called the vet and paid $90 for her to give him a shot and stand there until she was sure he was dead. If I had it to do over, I would use a bullet. It would be much faster, cheaper, and less stressful for the animal, who did not want a stranger in his pen or a shot which I am unconvinced was a painless death.
