She arrived at the Sanctuary in 2017, and her story became a landmark in the history of animal rights, as she was the first chimpanzee in the world to be freed from a zoo and transferred to the Sanctuary through a Habeas Corpus.

Cecilia lived for many years at the Mendoza Zoo in Argentina, where, after the death of her two companions, she remained in a precarious enclosure, very lonely and sad for years.

When Cecilia arrived at the Sanctuary, she was apathetic and very introspective, with no facial expressions or vocalizations typical of her species. After a few months, Cecilia adapted and had the opportunity to integrate and share the enclosure with the chimpanzee Marcelino, a young male who was also waiting for a companion.

Today, she is completely different, very expressive and active, as chimpanzees are. She enjoys watching her neighbors and lives in harmony, alternating moments, with her companions Marcelino and Miguel.
