More than 100 million animals—including mice, rats, birds, fish, rabbits, guinea pigs, farm animals, dogs, cats, and non-human primates—are used as experimental subjects each year throughout the world.

Humane Society International (HSI) is committed to reducing that number to zero through the use of science, law, educational outreach, government lobbying, and the support of more than 10 million members worldwide to promote more valid and humane methods of scientific research and product testing.

Animals experiments are a particular focus of HSI's European Union office.

	Campaigns HSI has a number of campaigns aimed at replacing animal use in experiments.
	Scientific Research Even animal research for “medical purposes” tends to be far from relevant to human health.
	Product Testing The use of animals in product testing figures prominently in the animal experiments controversy.
	Failings of Animal Experiments Animal “models” often do not correctly predict real-world diseases and chemical effects on people.
	Alternatives “Alternatives” result in replacement or reduction of animals used, or refinement of techniques to minimise pain.
	Regulation of Animal Experiments Key laws, regulations and guidelines governing animal experiments around the globe.
	Animal Use Statistics More than 100 million animals are used as experimental subjects each year throughout the world.
	Species Used in Experiments Animals used in experiments are as capable of feeling pain and frustration as our pets, explains The Humane Society of the United States.
