Abstract

Provided are animal containment systems and components, including single-use animal containment cages and modular rack units. Also provided are methods for assembling and using components of the animal containment systems.

Claims

1. A ventilated thin-walled rodent containment cage comprising a base and a cover, wherein:

the cover and base are constructed from a polymer;

the base comprises a wall or walls and a bottom;

the wall or walls of the base are 0.01 to 0.08 inches thick;

the cover comprises an air inlet aperture and an air exhaust aperture;

the wall or walls and sidewalls of the base are substantially imperforate;

the air inlet aperture is in effective connection with a blower, or the air exhaust aperture is in effective connection with a vacuum, or the air inlet aperture is in effective connection with a blower and the air exhaust aperture is in effective connection with a vacuum; and

the cage comprises a baffle disposed between the air inlet aperture and the air exhaust aperture in the cage, wherein the baffle, the air inlet aperture and the air exhaust aperture are configured to allow air to enter the cage downward from the air inlet aperture, flow under the baffle in proximity to the bottom of the cage, and exit the cage upward through the air exhaust aperture in a substantially U-shaped flow pattern.

2. The rodent containment cage of claim 1, wherein the baffle is one or more surfaces of a food tray.

3. The rodent containment cage of claim 1, which comprises a filter in effective connection with the cover.

4. The rodent containment cage of claim 3, which comprises a filter shield, wherein:

the filter shield is between the interior of the cage and the filter, and

the filter shield comprises a surface with apertures that is offset from the filter and covers the filter.

5. The rodent containment cage of claim 1, wherein the cage is self-supported in a rack.

6. The rodent containment cage of claim 5, wherein the cage is one of a plurality of self-supported-cages in a rack.

7. The rodent containment cage of claim 1, wherein the polymer is polyethylene teraphthalate.

8. The rodent containment cage of claim 1, wherein the polymer is polyvinyl chloride.

9. The rodent containment cage of claim 1, wherein the polymer is polyethylene.

10. The rodent containment cage of claim 9, wherein the polymer is high-density polyethylene.

11. The rodent containment cage of claim 1, wherein the polymer is polyethylenefluoroethylene.

12. The rodent containment cage of claim 1, wherein the polymer is polystyrene.

13. The rodent containment cage of claim 12, wherein the polymer is high-density polystyrene.

14. The rodent containment cage of claim 1, wherein the polymer is an acrylnitrile butadiene styrene copolymer.

15. The rodent containment cage of claim 1, wherein the polymer is polypropylene.

16. The rodent containment cage of claim 1, wherein the air inlet aperture allows for an air flow through the cage at a rate of about 5 cage exchanges per hour to about 60 cage exchanges per hour.
