Virginia Commonwealth University's animal inventory, compiled by the United States Department of Agriculture in November 2018, shows over 220 animals being kept by the University as subjects of experimentation. The most prevalent animals at VCU are rabbits (117), pigs (64), and primates (36).

In the span of 1 year, the number of rabbits kept at VCU for experiments has decreased by 72 and the number of primates by 5. Where did they go? What happened to them?
