Our facility wanted to transition from open top shoe box rodent cages to ventilated caging. A study was undertaken to #1: determine the time difference of performing typical study-related activities when rodents (rats and mice) are housed in a ventilated rack from Animal Care Systems (ACS) versus when housed in regular open-top shoe box bins and #2: determine whether corticosteroid levels (stress level indicator) and in-life parameters differ between the two different caging systems.
