Cinta

CINTA

The Three Squares Inc. (TSI) team adopted Cinta through the Borneo Orangutan Survival Foundation, an Indonesian non-profit dedicated to the conservation of the Bornean orangutan and its habitat.

Cinta was rescued from an area that had been cleared by an oil palm company. When found, she was apparently motherless, screaming, and shivering.

When she arrived at her rehabilitation facility, she was greeted by a special guest - former President of Indonesia, Megawati Soekarnoputri. The former President named the new baby Cinta, which means 'love' in Indonesian, a fitting name given that her rescue took place on Valentine's Day

Mema

MEMA

The Three Squares Inc. (TSI) team adopted Mema through the Borneo Orangutan Survival Foundation, an Indonesian non-profit dedicated to the conservation of the Bornean orangutan and its habitat.

Mema was found by a local villager who claimed to have come across her whilst searching for firewood in a burned peat area. He took Mema to the local village chief, who reported the finding. When found, she was a weak baby weighing only 2.3 kilograms.

Under the care of the Borneo Orangutan Survival Foundation, Mema has developed a playful and friendly nature that allows her to easily make friends with newcomers.
