Background

According to the organization's website, Humane World for Animals "has been a leader of the animal protection movement, tackling the root causes of animal cruelty and suffering to drive permanent change and create a better world for all animals around the globe."[2]

Humane World for Animals was established as the National Humane Society in 1954 by Fred Myers and a group of former members of the American Humane Association (AHA), a nonprofit organization that aims to support public policies that protect children and animals.[3] The group, which was later renamed the Humane Society of the United States, began advocating to protect animals from what the group considers to be cruel conditions, such as fighting operations, puppy mills, inhumane slaughterhouses, and factory farms.[4]

In 2025, the group changed its name from the Humane Society of the United States to Humane World for Animals.[5] The organization said the change was so "we can reach more people, expand our impact and build a future where all animals are treated with the compassion they deserve."[6]

According to the organization's website, the Humane World Action Fund "works to ensure that animals have a voice throughout the halls of Congress and with the thousands of federal and state lawmakers who can help address the suffering and abuse of animals."[8]

Humane World for Animals has supported legislative efforts to mitigate what the group considers to be animal cruelty practices at the state and federal levels. The following list is a selection of federal legislation supported by Humane World for Animals:[3]

Humane World for Animals spent $1,070,000 on federal lobbying in 2024, according to records compiled by OpenSecrets.[9]

In addition to national public policy advocacy, Humane World for Animals maintains a network of state directors to promote the organization's policy priorities at the state level.[10] At the local level, Humane World for Animals seeks to offer education and training programs to local animal shelters. The group also endeavors to provide direct care to animals through rescue efforts and a network of shelters, sanctuaries, and veterinary clinics.[11]
