About Us

Image of corporate building

Animal Care Systems manufactures the only motor-free rodent caging system in the industry. Combining “twice the mice” density with our unique carousel design, our caging provides a microenvironment that is free of noise, vibration and ultrasound, creating a variable-free environment. We have established a stellar reputation for our superior customer service and product support.

Established in 1997, Animal Care Systems is the first caging systems company in the industry founded by a veterinarian with experience in directing AAALAC-accredited animal care & use programs. Dr. Germain Rivard’s experience with animal facility planning, design and management produced the construction of the first Gene Transfer Technologies Training Center and Rodent Barrier Facility for genetically altered mouse colonies.
