Bio-containment animal cage system

A method of maintaining pressure in an animal cage system comprising the steps of:

• placing a bio-sensing self-sealing animal cage on a rack for supporting said cage;
• removably connecting an air supply means for supplying air to said bio-sensing self-sealing animal cage and an air exhaust means for removing exhaust from said bio-sensing self-sealing animal cage;
• measuring pressure in said bio-sensing cage with a pressure measurement means;
• and
• controlling said air supply means or said air exhaust means in response to the measured pressure in the bio-sensing cage, thereby maintaining a predetermined pressure in said bio-sensing cage.

A self-sealing animal cage comprising:

• a top section;
• a bottom section;
• and
• sealing means for sealing said top section to said bottom section,
• wherein a wall of said top section has a first rim at a periphery thereof, a channel is formed around an inner portion of said first rim and a wall of said bottom section has a rim at an upper portion thereof, a gasket seal received in said channel, wherein said rim of said bottom section being adapted to be pressed against said gasket seal for sealing said top section to said bottom section.

A self-sealing animal cage comprising:

• a top section;
• a bottom section;
• and
• sealing means for sealing said top section to said bottom section;
• a food and water suspension lid suspended within said self-sealing animal cage,
• wherein said food and water suspension lid comprises an edge, said edge having circumference which is slightly smaller than a circumference of an inner circumference of said bottom section of said self-sealing animal cage;
• and
• a plurality of wires connected to said edge, said plurality wire adapted to hold food and a water disperses.
