The Bio-Serv Certified Safe Harbor Mouse Retreat is a certified shelter for mice made of high temperature polycarbonate. It offers life-saving refuge during cage flooding events by providing an opportunity for escape to a higher level where mice can stay warm and dry. The bi-level design offers a platform for undersized weanlings to reach the food source on cage lids, as well as a means for submissive mice to find shelter and easily move away from dominant mice, thereby minimizing fighting injuries as compared to other shelters that trap the mice inside.
