The Marsh Designs rodent
monitoring cages are designed to maintain a better quality, less stressful
environment for experimental research subjects while allowing for continued
uninterrupted data acquisition.
The novelty of our cages
is that there is not a fixed, enclosed bottom, but rather the cage sits in a
separate tray. Several parallel, evenly spaced dowels are affixed horizontally
near the bottom of the cage and when in use, covered by the bedding material.
When the main cage is lifted out of the tray, the rods allow the soiled bedding
to fall below into the tray, while supporting the animal with fragile
head-mounted recording equipment. The tray can then be emptied and replaced
under the cage. Fresh bedding can then be added via the top of the cage. This
method eliminates the need to physically handle the animals, reducing the
overall stress of the animal. The animals are less likely to thrash around the
cage and risk damaging sensitive equipment that may have been surgically
implanted. This allows researchers to maintain a clean cage environment without
the need to restrain the animal, disconnect the animal from a tethered line
and/or stop any ongoing data collection. The ability to use natural bedding in
the Marsh Designs cage promotes the animals’ natural behaviors, leading to
longer and more sustainable data collection for experiments.
Rodents subject to
research can become anxious, temperamental and agitated. Our cages allow the
researcher to maintain a physical barrier between themselves and the rodent.
This provides a safer environment for the researcher by minimizing bite risks
and associated zoonotic diseases. This is especially beneficial to those with
allergies to rodents, minimizing direct contact with the rodents and/or the
bedding while changing cages.

Each Marsh Designs rodent
monitoring cage is manufactured from 100% clear, non-permeable acrylic. Precision
fabrication is achieved through a combination of CNC machining and laser
cutting each individual component. The components are then solvent bonded to ensure
rigidity and strength.
