Chimpanzees are wild, complex animals who live in family groups and form lifelong bonds.

In 2015, the federal government effectively ended the use of chimpanzees in medical research, making it possible for more than 700 chimpanzees to be retired from often painful and invasive research. But there is not enough space in existing sanctuaries. You can help us fight to give them the retirement they deserve

Chimpanzees are highly intelligent.

Chimps are one of only a few species who use tools to help them in the wild, such as employing sticks to dig insects and other snacks out of the ground and holes in trees. They also use hand gestures, facial expressions and sounds to communicate with one another.

Footage from our undercover investigation at New Iberia Research Center in La. showed evidence of severe distress of primates in isolation, including self-mutilation, revealing that animals are forced to endure anxiety and misery behind the razor wire of the research facility.
Did you know?

Chimpanzees share nearly 99 % of our genetic makeup, making them our closest relative—interestingly though, they are not considered to be relatives of the monkey family.

For every animal saved, countless others are still suffering. By stepping up for them, you can create a future where animals no longer have to suffer in puppy mills, factory farms, testing labs or other heartbreaking situations. Start saving lives today!
