According to the document, over 1.4 million animals were used in research in the United States in 2002, with rats and mice making up 90% of those animals. Most animals are used for a single experiment but some may be used in multiple experiments. Larger animals like dogs, cats, and primates typically live in wire cages while being used for research.
