Senator Wiener’s PET Act, Ending Harmful and Unnecessary Chemical Testing on Dogs and Cats, Passes Assembly Judiciary Committee

July 6, 2021

SACRAMENTO - Senator Scott Wiener’s (D-San Francisco) legislation, Senate Bill 252, also known as the PET (Prohibiting Extraneous Testing) Act, passed the Assembly Judiciary Committee by a vote of 10-0. It will now head to the Assembly Appropriations Committee. 

The PET Act ends the suffering of cats and dogs by prohibiting these household pets from being used in toxicity tests for products such as pesticides, food and color additives, and drugs. This bill exempts the testing of pet medications and pet products and testing for biomedical research and vaccines. Additionally, SB 252 does not impact testing required by federal rules or recommendations.

Studies show that animal toxicity tests are unreliable, do not truly ensure human safety, and have serious scientific limitations. For example, nearly 90 percent of drugs first tested on animals end up failing when subsequently tested on people, with about half failing due to unanticipated toxicity when tested on humans. Much of the current toxicity testing on these animals is inhumane, unnecessary, and ultimately does not further scientific research on toxicity in humans. 

Toxicity testing exposes animals to chemicals (including pharmaceuticals, industrial and consumer products, and food additives) as an attempt to understand what harms may be caused to humans by these chemicals. This testing is frequently excruciatingly painful for animals. According to the Physicians Committee for Responsible Medicine, this testing varies in duration, and animals are observed for toxic effects including: vomiting, diarrhea, convulsions, respiratory distress, appetite or weight loss, rashes, salivation, paralysis, lethargy, bleeding, organ abnormalities, tumors, and even death. 

In California, according to the U.S. Department of Agriculture (USDA), there are approximately 600 dogs located in ten different facilities across the state where this toxicity testing occurs. These canines are bred to live their entire lives confined in laboratory settings and are forced to undergo product testing that does not ensure human safety, or even eliminate the need for eventual human testing. The testing can include situations in which chemicals are forced down a dog’s throat, or into their lungs. Some tests even involve intentionally administering a drug or chemical overdose to a dog, and other tests involve administering chemicals over a prolonged period, causing slow and painful deaths. The bill will put an end to those tests and ensure that cats are not subject to the same conditions.

The PET Act prohibits this unnecessary and harmful testing, while allowing for essential testing involving drugs and products for pets, and for biomedical research. Biomedical research is defined as research related to physical or mental diseases, impairments, chronic conditions, and the development of biomedical products or devices. Medical research does not include research related to the development of drugs. 

The PET Act is sponsored by the Humane Society. Senator Sydney Kamlager (D-Los Angeles) Assemblymembers Ash Kalra (D-San Jose) and Richard Bloom (D-Santa Monica) are co-authors of the legislation.

“It’s heartbreaking and unacceptable that we still subject dogs and cats to unnecessary toxicity testing,” said Senator Wiener.  “Toxicity testing – much of which has little or no medical value – causes pain, suffering and even death in the animals on which it’s performed. We need to ensure our dogs and cats aren’t undergoing this unnecessary and inhumane testing, and are instead given good, long lives.”
