PAAW Act

HR 4698, the PAAW Act, prohibits the National Institutes of Health (NIH) from conducting or funding research that causes significant pain or distress to dogs or cats. This directly affects NIH-funded studies involving these animals, specifically banning research assigned to USDA-defined severe pain categories (D or E). The law takes effect 90 days after enactment and relies on existing USDA pain classification standards under the Animal Welfare Act. It creates a clear policy change limiting NIH research involving dogs and cats when severe pain is anticipated.
