Cows
Parvati is cow who is part Scottish Highland and part Charlois. She was originally in a petting zoo that sent her to a feedlot for slaughter. Now that she is at Ching Sanctuary, she is leading a very happy existence with her husband Nandi.
The purpose of a feedlot is to fatten animals before they are slaughtered. The animals are well fed but that is about the only care they get. If an animal is sick, it is not given veterinary care. It would cost the people at the feedlot too much. A horse will only get care if it is injured to the point that it can't walk. This is because it is illegal to send a horse to slaughter if it is blind or can't walk onto the truck itself.
Petting zoos monitor how much money is made from each animal by the coin operated feeding machines in their confined areas. If an animal is not "performing", in other words not taking in enough money, it is sent to slaughter. There are many reasons why an animal is not drawing in enough money. There may be a more aggressive animal competing for food, a cuter baby animal that gets more attention, or the animal may not enjoy the food. None of these reasons is justification for sending an animal to become food.
