Picture the dog at your feet, the guinea pigs or mice you had as pets growing up, or the birds at the feeder in your yard. Now imagine 25 million of animals just like these living in small laboratory cages and being deliberately sickened over the course of weeks, months, or even years--and then killed.


If animal experimentation was the hallmark of 20th century biomedical research, sophisticated non-animal methods are likely to characterize 21st century research. Many humane state-of-the-art alternatives to animal experiments have already been shown to be effective in advancing medical progress, cutting research costs, and eliminating animal suffering.

The HSUS is at the forefront of promoting these research methods and their continued development, as well as ending some of the most inhumane research practices. Until the day when animals are no longer used in harmful experiments, the HSUS, with your help, also strives to gain stronger legal protection for animals used in research, and seeks to limit animal use and suffering. Right now, approximately 95% of the animals used for research aren't afforded even the minimal protections of the Animal Welfare Act.
