A baby orangutan in Indonesia is currently undergoing treatment after being found outside in a cardboard box, presumably left to die.
In fact, the U.K.-based International Animal Rescue, or IAR, which is overseeing recovery efforts, notes on its Facebook page that this is "one of the most shocking cases of animal cruelty and neglect we have ever seen."
A post on the group's website reveals that he was in such bad condition they initially thought he was dead: "He was lying corpse-like with his arms folded across his chest and this, along with a lack of hair and grey flaking skin, made him look almost mummified in his cardboard coffin."
The nearly five month-old orangutan who they eventually named Gito is reportedly being treated for dehydration, malnutrition, and a parasitic skin infection.
He is believed to have been kept as a pet by the head of a nearby village and given only condensed milk to eat which caused his health to deteriorate.
The group notes that forest fires in parts of Indonesia are destroying wild orangutans' habitats and are causing more members to be captured by humans.
