Founded in 1983 by Dr. Elliot Katz DVM, In Defense of Animals is an international animal rights and rescue organization dedicated to protecting the rights, welfare and habitats of animals.
We are supported by a network of tens of thousands of determined activists, dedicated volunteers, interns and donors. We work to expose and end animal experimentation; protect wildlife and restore balance in their natural habitats; end the exploitation and abuse of wild species living in captivity, protect domestic and wild species worldwide from abuse and slaughter for food, conduct cruelty investigations and rescue operations, and provide veterinary care for sick, abused and orphaned animals in our natural habitat sanctuaries.
