Senator Wiener Introduces the PET Act to End Harmful and Unnecessary Testing on Dogs and Cats

February 25, 2021

SACRAMENTO - Senator Scott Wiener (D-San Francisco) has introduced new language for Senate Bill 252, also known as the PET (Prevent Extraneous Testing) Act. The PET Act ends the suffering of dogs and cats 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 products. Additionally, SB 252 does not impact testing required by federal statutes or medical research in the state.

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. 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 required 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 of the United States. Assemblymembers Ash Kalra (D-San Jose) and Richard Bloom (D-Santa Monica) are co-authors of the legislation.

“Dogs and cats should not be subjected to unnecessary and inhumane toxicity testing that doesn’t have useful health outcomes,” said Senator Wiener. “We should make sure that if testing is done on dogs and cats, that it is humane and has an actual medical value. Animals deserve better treatment and should not be subjected to harmful testing simply because they can’t say no.”

“The life of a dog used in toxicity testing is one filled with fear and unnecessary suffering. This bill can protect hundreds of dogs each year. With modern technology, there is no need for these antiquated tests,” said Sabrina Ashjian, California State Director for the Humane Society of the United States. “We are so thankful to Senator Wiener for proving that once again, California is paving the way for animal welfare,”
