Is it true that most research involves non-human primates?
No. The vast majority of research animals are mice and rats bred for this purpose. Dogs, cats, and non-human primates together account for less than one-half of one percent of the total, and this number has declined for more than 25 years. Since 1979, the number of dogs and cats needed in animal research has declined by more than 50%. The number of non-human primates needed represents less than .2% (.18% in 2004) and has remained relatively constant—in the 50,000 per year range—for the past decade.
