Sick psycho bitches. They never considered the horse a pet. Just a utility. When the utility served its purpose it was disposed of - not even in a humane way but in a most gruesome manner to extract every bit of value out of the poor animal, even in its dying moments. That’s what the horse got for being a “pet”.
Most horses are a utility. So are most cattle, pigs, sheep, etc.
We eat meat. You expect lions to eat their veggies?
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.
