Animals should never be held captive, experimented upon against their will, or slaughtered for convenience. Please support our work urging agencies and companies that engage in animal experimentation and captivity to cease!
In Defense of Animals is on the cutting edge of legal strategy and litigation for animals and the environment. We get the job done! IDA's nine-year campaign against the infamous Coulston Foundation, once the largest chimpanzee research center in the world ended with the forced bankruptcy of the foundation, and hundreds of chimpanzees and monkeys saved from the horrors of vivisection.
We work to end vivisection and find humane alternatives globally!
We couldn't carry out our life-saving work without the gifts of our generous supporters. Please, consider making a donation to In Defense of Animals, and help us continue to fight against vivisection. All gifts, no matter how big or small, make a difference.
Did you know that 98% of people who have signed our Action Alerts have never made a donation?
We are so grateful for every action taken by each and every one of you. But, can you imagine what we could do if each and every one of you who signed one of our alerts was also able to make a small donation, even just once?
The animals who depend on us need your support now more than ever. If every In Defense of Animals supporter were to donate just $5 today, our work on behalf of animals would be funded for the entire year or more! Your gifts support our critical work advocating the passage of laws improving animal welfare and defending animal habitat, as well as our hands-on work to help abused, neglected, and abandoned animals at our sanctuaries. It only takes a minute and gifts of any size are appreciated.
If you are already an In Defense of Animals donor, we would like to graciously thank you and let you know that your support saves lives.
