"In Defense of Animals has set the standard for integrity and results in animal advocacy. In a world in which too many look away, IDA has been on the cutting edge of front-line activism to end abuse and exploitation. No organization has done more to uphold the principles of justice for our animal friends."

Jeffrey Masson

Author, When Elephants Weep


"When IDA picks a target, they go after it. Whether it's saving seals from slaughter in South Africa or rescuing stolen greyhounds from torture in medical laboratories or stopping the killing of thousands of animals by Procter & Gamble, IDA has been on the front lines of the fight to end animal exploitation."

"Congratulations Elliot Katz, and all of the wonderful IDA team. Congratulations on the long years of hard work that have led to the closing of the infamous Coulston labs and the liberation of the chimpanzees and monkeys who have suffered so horribly."

Human history is full of inspiring stores of those who achieved the impossible. Those of us who believe in the intrinsic worth of each chimpanzee, each monkey, can take heart as we celebrate the inspiring victory of IDA.

With warmest congratulations to you all,"
