About ChimpCare

Today in the United States there are over 2,000 chimpanzees living in a variety of circumstances: from zoos (both accredited and non-accredited), laboratories and sanctuaries to lives as pets and performers under private ownership. While many of these chimpanzees enjoy appropriate care and management and the security of long-term housing, many others do not. Furthermore, there is very little known about many of these chimpanzees, and there has been relatively little communication between these communities.

Project ChimpCARE is a non-partisan group committed to improving the wellbeing of chimpanzees, regardless of current circumstances, and opening the lines of communication between disparate groups to achieve this singular goal. Our objectives are based on the approach that accurate information is the basis for effective change. We seek to:

The future for many chimpanzees in the United States is uncertain. Legislation is changing. Finances are unstable. Project ChimpCARE seeks to collaborate with anyone invested in caring for chimpanzees and to build a better future for chimpanzees.
