The Symposium on Social Housing of Laboratory Animals will be held on March 17–18, 2016, on the campus of the University of California, Davis. The meeting, co-hosted by the Johns Hopkins Center for Alternatives to Animal Testing, the UC Davis School of Veterinary Medicine, the US Department of Agriculture, and the National Institutes of Health’s Office of Laboratory Animal Welfare, is the third held on this topic, which is so critical to the well-being of animals in research. The agenda is still being finalized, but will include presentations on the socialization and welfare of mice, fish and amphibians, rabbits, macaques, and swine, as well as presentations on dog cognition, social housing during experimentation, and the use of personality to predict compatibility. AWI will table at the event, providing complimentary copies of our publications for personnel involved in the care and treatment of animals in the laboratory—including our newest book, Comfortable Quarters for Laboratory Animals. Additional information on the conference and registration can be found at http://caat.jhsph.edu/programs/workshops/social_housing.html. Please note that space is limited and registration closes on February 29.
