Optirat GenII Standard Cage Bottom

Highest Rat IVC Cage Density in the Industry

This uniquely shaped cage is designed to provide the highest density of caging per square foot of room space and provides a multitude of benefits: laminar airflow, slow air movement, removal of waste gas from the entire cage, and a wide front area for easy viewing of rats and other rodents.

Recommendations: The lack of motors, vibration and noise means this cage is particularly well suited for rats in behavior studies, mice who need complex, enriched environments including many structures such as running wheels, shelters, ramps, and tubes, and exotic rodentia such as deer mice.
