Gentlemen,
while giving one’s pet away for feeding carnivores at a zoo might be questionable, please do take into account that the pony had indeed been put to sleep before being given to the carnivores in the zoo.
I’d have to differ there. The vet that I donate euthanized livestock to stipulates that the subject has to be shot, as the chemicals in euthanasia drugs would be consumed in the meat. A bullet to the head is generally more humane that the drugs anyway. Sometimes the drugs will illicit an undesired result.
