The original M.I.C.E. system is a modular, high-density vented caging system for housing rodents. These systems are available in a variety of sizes, from the smallest 14-cage system, ideal for small studies and experiments, to large 140-cage racks suitable for installation in medium to large animal rooms. Each size of rack is based on multiples of the 14-cage module.

M.I.C.E. systems are available in both single- and double-sided versions. The M.I.C.E. system is the only rodent caging system in the world validated for Microenvironmental comfort, Isolation, Containment, and Enrichment (M.I.C.E.). The M.I.C.E. rack is vented using the exhaust of a building's HVAC system, with a natural convective assist from the populated cages themselves. Without motors or blowers, airflow is not disrupted in the case of power failure — a unique feature that separates the M.I.C.E. system from ones ventilated by motorized blowers.
