About Us

See Our Gifts

Founded in 1983 by veterinarian Elliot Katz, In Defense of Animals' staff have worked tirelessly to protect the rights, welfare and habitats of animals through undercover investigations, rescue operations, grassroots activism, media campaigns, boycotts, lawsuits and legislation. Sanctuary and veterinary care are provided through our field offices in Portland, OR; our sanctuary for abused animals in rural Mississippi; our chimpanzee forest sanctuary in Cameroon, Africa; and our veterinary hospital in Mumbai, India.


To represent the interests of animals; to end individual, governmental, and corporate exploitation and abuse of animals by elevating their status beyond that of mere commodities, property and things; and to protect, defend and advocate for the rights, welfare and habitats of animals.


To care for the injured and abused, and to prevent animal cruelty wherever it might exist, IDA staff conduct programs in the United States and around the world. IDA-Africa fights the chimpanzee bush meat trade while running a chimpanzee forest sanctuary in Cameroon, Africa. Project Hope, our sanctuary for abused animals in Grenada, Mississippi, has given sanctuary and saved the lives of thousands of abused and abandoned animals. IDA-India, through its veterinary hospital and spay/neuter clinic, cares for the street dogs and donkeys of Mumbai, India. IDA campaigns include exposing and ending the cruelties of the vivisection, factory farming, foie gras, and fur industries; the Korean dog and cat meat trade; the exploitation and suffering of animals in rodeos, zoos and circuses; and the killing of homeless animals in our nation’s shelters. Our Guardian campaign promotes respect and responsible care of animal companions by promoting the use of the term “animal guardian" instead of the term “animal owner." IDA’s Undercover TV airs on over 80 community access channels across the nation, exposing viewers to the terrible realities of the factory farming, fur, circus, and vivisection industries. Visit to learn more about IDA’s far reaching campaigns and programs.


Our accomplishments include: canceling the slaughter of thousands of seals off the coast of South Africa; creating a chimpanzee sanctuary in Cameroon, Africa and a sanctuary in Mississippi that has saved the lives of thousands of abused animals; closing the Coulston Foundation, freeing hundreds of chimpanzees from the torment of vivisection; closing abusive animal shelters and puppy mills; ending crack cocaine experiments on monkeys, brain cancer experiments on puppies, bone-breaking experiments on greyhounds, and vomiting experiments on cats; saving hundreds of buffalo and horses from being sent to slaughter; freeing 40 dolphins from Japanese fishermen about to kill them.

A Gift Card

Surgery for a Pony

From India's Streets

Your gift will provide veterinary care to one horse who would otherwise be left to suffer and die an early and often painful death. Each month, IDA India provides nearly 200 treatments for Mumbai’s horses, from dressing wounds and setting sprains to treating laminitis.


Sponsor an Activist

500 Anti-Fur Leaflets

Your gift will pay for 500 anti-fur leaflets to be handed out by one of our volunteers. IDA provides these leaflets to anti-fur activists throughout the country for demonstrations and anti-fur outreach in an effort to educate the public on the horrors of the fur industry.


Emergency Surgery

For an Animal in India

Your gift will help provide relief for one injured or sick animal with help from IDA India’s ambulances, mobile clinic, and veterinary facilities. Each month, IDA India treats over 200 dogs and cats for wounds, fractures, malnourishment, infestation, and other problems that would otherwise lead to an early and painful death.


Stop Overpopulation

Spay/Neuter in India

Your donation will provide one desperately needed spay/neuter surgery. IDA India performs nearly 1,000 spay/neuter surgeries a month! While much work remains to be done, these actions are crucial to reducing the huge population of homeless animals in India.


Care for an Animal

Help a Rescued Animal

This gift will supply an abused cat or dog with bedding, treats, toys, and nutrition – things that most of us take for granted but that many new arrivals will experience for the first time.


Puppy Mill Rescue

Support a Rescued Dog

Your gift will provide the necessary support to rescue a dog, like the one pictured here who we rescued from the recent puppy mill bust, from the perilous conditions of a puppy mill. Costs include transportation, extra staff, grooming, and veterinary care. These steps ensure that an exploited dog may finally have the life he or she deserves.


Initial Vet Exams

For a Puppy or Kitten

This gift will afford Project Hope puppies and kittens a crucial step in their path to adoption with a much-needed veterinary exam. Initial exams include checking their weight, temperature, heart, lungs, internal organs, and ears. Pre-adoption examinations for puppies and kittens are often a veterinarian’s favorite part of the job.


Give Parvo Vaccine

Help a Rescued Puppy

Your gift will help one Project Hope Sanctuary puppy grow up healthy and happy. Once the vaccination has been completed, they can be put up for adoption to live the life they so richly deserve.


Feed Watermelons

Give Pigs a Treat!

Your gift will provide the rescued pigs with their absolute favorite food. As soon as the pigs see Doll with the watermelons, they practically knock her over as they race to bury their noses into the fruit. Your gift will bring pure joy to these once neglected animals.


Feed an Emu

One Month of Feed

Your gift will feed Ivan or one of the other rescued emus at Project Hope. Because each emu consumes 3 pounds of food a day, your gift will provide 270 pounds of feed to an emu, providing him or her with the essentials to the highlight of the day for an entire month.


Save A Rescued Cat

One Month of Care

Your donation will focus on proper nourishment for one of Project Hope's cats, like Jennifer, pictured here. Your gift will also go to veterinary care, to keep cats like Jennifer healthy and happy. There is no better gift to give than the gift of a second chance for one of Project Hope's cats. These cats have been abused, abandoned, and on death's door. They've found...
