Divided caging had significantly fewer aggressive behavior events than standard caging (A), and significantly fewer bite wounds than standard caging (B). Open dots indicate bite wounds following the introduction or removal of a cage divider. Dashed line indicates the cage change time point when the cage divider was introduced or removed from standard or divided caging, respectively. (C) The correlation between the number of aggressive events and bite wounds in a cage was positive and significant. Individual cage conditions (standard: blue; divided: orange) and time points (housing: filled circle; after addition (+) or removal (-) of a cage divider: open circle) are uniquely identified
