Tenure: 104th–119th Congresses
Years of Service: 1995–Present
Rep. Zoe Lofgren has compiled one of the most extensive and consistent animal protection records in Congress. Over more than three decades in the House of Representatives, she has repeatedly supported legislation aimed at protecting wildlife, strengthening anti-cruelty laws, improving standards for farm animals, reducing animal testing, and addressing emerging threats to both animals and public health. While she is often recognized for her work on technology, immigration, and intellectual property issues, her record demonstrates a sustained commitment to animal protection across a remarkably broad range of policy areas.
What distinguishes Lofgren from many lawmakers with favorable voting records is the breadth of her affirmative legislative engagement. Rather than simply supporting animal protection measures when they reach the House floor, she has repeatedly cosponsored legislation addressing specific forms of cruelty, wildlife exploitation, public health risks, and animal welfare concerns.
Lofgren is a cosponsor of H.R. 3683, legislation addressing animal cruelty concerns through strengthened FBI enforcement authority. She is also a cosponsor of the No Flight, No Fight Act, which would crack down on the transportation of animals for fighting ventures and strengthen enforcement against organized animal cruelty. The legislation complements broader efforts to combat dogfighting, cockfighting, and related criminal enterprises.
She has also cosponsored the LEAD Act, legislation designed to reduce wildlife exposure to toxic lead and encourage a transition toward safer alternatives. Lead poisoning remains one of the most significant human-caused threats to many wildlife species, including condors, eagles, swans, loons, and other scavenging and waterbird populations. Her support for the legislation reflects a longstanding commitment to wildlife conservation and science-based policymaking.
Lofgren has additionally cosponsored the MINK Act, legislation aimed at addressing concerns associated with mink farming and the risks such operations can pose to both animal welfare and public health. The legislation emerged in part from concerns about disease transmission and the conditions under which mink are raised in commercial facilities.
Her support for H.R. 6864, the Supporting All Wildlife (SAW) Act, further demonstrates a broad interest in wildlife protection and conservation. Taken together, these measures show engagement across a wide spectrum of animal protection issues that extends far beyond routine voting.
Lofgren’s voting record on recent benchmark animal protection issues has been consistently favorable. She voted against H.R. 845, the Pet and Livestock Protection Act, which would remove federal Endangered Species Act protections for gray wolves. She also voted against H.R. 556, the Protecting Access for Hunters and Anglers Act, preserving federal authority to regulate lead ammunition and lead fishing tackle on federal lands and waters. Those votes aligned with efforts to maintain federal wildlife protections and reduce preventable wildlife mortality.
She also voted against the Moore Amendment, which sought to create an exemption from the federal prohibition on commercial greyhound racing. Her vote supported maintaining federal protections that have helped bring commercial greyhound racing to an end across much of the country.
On farm-animal welfare and food-system issues, Lofgren voted against the Greene Amendment, which sought to prohibit federal support for cultivated meat and related technologies. By opposing the amendment, she supported continued research into alternatives that could reduce reliance on conventional animal agriculture and decrease the number of animals raised and slaughtered for food. She also voted against the Farm, Food, and National Security Act, which included provisions that would preempt state farm-animal welfare laws such as California’s Proposition 12 and Massachusetts’ Question 3.
Lofgren’s record reflects an understanding that animal protection is not confined to a single issue area. Her legislative support spans wildlife conservation, anti-cruelty enforcement, public health, farm-animal welfare, and innovation in food systems. Few members of Congress have demonstrated such sustained engagement across so many facets of animal protection policy.
Taken as a whole, Lofgren’s record places her firmly in the Champion of Animal Protection category. Her extensive legislative involvement, long-standing support for animal welfare initiatives, and consistently favorable voting record make her one of the strongest allies for animals in the House of Representatives.

The bill would strengthen enforcement of the Horse Protection Act and help end the cruel practice of “soring” Tennessee Walking Horses, Racking Horses, and Spotted Saddle Horses. Soring involves intentionally inflicting severe pain on horses’ legs and hooves through caustic chemicals, chains, pressure devices, or other abusive methods to force an exaggerated, high-stepping gait known as the “Big Lick.” The motion was agreed to by a vote of 304–111, exceeding the two-thirds majority required under the suspension of the rules procedure. An “Aye” vote is the pro-animal position.
✅ Voted “Aye” Big Cat Public Safety Act, H.R. 263 (House Roll Call Vote 415), to end the private possession and commercial breeding of lions, tigers, leopards, cheetahs, jaguars, cougars, and other big cats while prohibiting public contact with these animals. The legislation targeted the exploitative cub-petting industry and roadside zoos, where big cats are repeatedly bred, handled, and discarded, while strengthening protections for both animals and public safety. An “Aye” vote is the pro-animal position.
116th Congress
✅ Cosponsor of the Big Cat Public Safety Act, H.R. 1380, to prohibit private ownership and breeding of lions, tigers, and other big cats while restricting public contact with these dangerous wild animals. The bill was designed to curb the exploitation of big cats in roadside zoos and cub-petting operations, improve animal welfare, and enhance public safety by limiting private possession of these species.
✅ Voted “Aye” on the H.R. 1380 – Big Cat Public Safety Act (House Roll Call Vote 232), legislation to prohibit private ownership and breeding of lions, tigers, and other big cats while restricting public contact with these dangerous wild animals.

The House passed the bill 272–114. An “Aye” vote is the pro-animal position.
✅ Voted “Aye” on the Stevens Amendment (House Roll Call Vote 373) to the FY2020 Commerce, Justice, Science, and Related Agencies Appropriations Act, allocating $2 million to create an Animal Cruelty section within the Department of Justice. An “Aye” vote is the pro-animal position because it supports stronger federal enforcement of existing animal protection laws.
✅ Voted “Aye” on the Buchanan Amendment (House Roll Call Vote 380) to the FY2020 Interior, Environment, and Related Agencies Appropriations Act, prohibiting the Department of the Interior from issuing import permits for trophies of threatened elephant and lions from Tanzania, Zambia, and Zimbabwe. An “Aye” vote is the pro-animal position because it supports stronger protections for threatened wildlife by restricting the import of hunting trophies.
115th Congress
✅ Cosponsor of the Dog and Cat Meat Trade Prohibition Act, H.R. 1406, bipartisan legislation to prohibit the slaughter of dogs and cats for human consumption and ban the sale, transport, possession, and trade of dogs, cats, and their parts for that purpose. The bill established federal criminal penalties to ensure the United States maintains a clear prohibition on the dog and cat meat trade.
✅ Cosponsor of the Humane Cosmetics Act, H.R. 2790, bipartisan legislation to phase out animal testing for cosmetics and prohibit the sale of cosmetics developed or manufactured using new animal testing. The bill encouraged the use of modern, non-animal testing methods while helping align U.S. policy with the growing international movement to end cosmetic testing on animals.
✅ Cosponsor of the Prevent All Soring Tactics (PAST) Act, H.R. 1847, to strengthen enforcement of the Horse Protection Act and help end the cruel practice of “soring” Tennessee Walking Horses, Racking Horses, and Spotted Saddle Horses.

✅ Voted “Nay” on H.J. Res. 69, a Congressional Review Act resolution (House Roll Call Vote 98) to overturn an Obama administration rule protecting wildlife on National Wildlife Refuges in Alaska. The rule prohibited inhumane predator-control practices, including killing bear cubs and wolf pups in their dens, baiting bears with food to shoot them at close range, and aerial shooting of wolves and other predators. The resolution passed Congress and was signed into law, eliminating these federal wildlife protections. A “Nay” vote is the pro-animal position because it sought to preserve safeguards against some of the cruelest and most unsporting predator-killing practices on federal refuge lands.
✅ Voted “Aye” on the Roskam–Blumenauer Amendment (House Roll Call Vote 202), to H.R. 2, the Agriculture and Nutrition Act of 2018, to strengthen the federal animal fighting law by clarifying that its prohibitions apply throughout all U.S. territories. The amendment closed a legal loophole that had allowed organized dogfighting and cockfighting to continue in certain U.S. territories despite being illegal elsewhere in the United States. An “Aye” vote is the pro-animal position because it strengthened federal protections against organized animal fighting.
