He was raised by a family as a pet and was later sent to zoos in Curitiba and then Sorocaba. When he lived at the zoo he had severe psychiatric disorders and severely self-mutilated, biting his legs and tearing off pieces of his own skin and musculature. For the zoo, Caco’s fate would be euthanasia as he could not improve under those living conditions. He was then taken to Sanctuary and his life changed completely. Upon arriving at the Sanctuary, in 2002, Caco underwent drug treatment, but the most important thing was to live directly with the chimpanzee Jully and indirectly with other neighbors of the same species. This was fundamental and made Caco present a complete improvement in his clinical condition in a few months. Since then, he has not shown signs of any psychiatric problem and lives peacefully with his partner Jully. Caco is very playful, curious and affectionate with his caregivers. He enjoys grooming and playing tag, daily showing his joy at having had another chance to live in peace and harmony, leaving his past of suffering behind.
