Since 1954, we’ve been at the forefront of the fight to end animal cruelty and suffering. By tackling the root causes of the issue, we’ve driven lasting change for millions of animals around the world. From pioneering laws that protect animals to groundbreaking investigations that expose hidden abuse, our history is a testament to our commitment to creating a more humane world.
