When rescuers at International Animal Rescue responded to a recent call, they had no idea it would be “one of the most shocking cases of animal cruelty and neglect” they had ever seen. An orphaned baby orangutan, left to die in a cardboard box, had nearly been mummified by the sun and malnutrition.

Amazingly, the 5-month-old infant, whose name is Gito, was still alive. But there wasn’t any time to waste—he needed medical care, and he needed it right away.
