Abstract

A rodent cage including a cage bottom having a plurality of integral side walls, a floor and an open top end. A peripheral lip extends continuously around the top end. A pair of recesses are disposed on the peripheral lip. A feeder assembly has a frame and at least one section descending therefrom. The frame has pair of flanges extending therefrom so that when the feeder assembly is disposed in the cage bottom the pair of flanges are mated with the pair of recesses, respectively. A bonnet is dimensioned in size for sealing the top end of the cage bottom. A lock is disposed on the bonnet for preventing rodents housed in the cage from displacing the bonnet from the cage bottom.

Claims

1. A feeder assembly for use in an animal cage, comprising:

a frame;

at least one support descending from said frame;

a pair of flanges extending from said frame to support said frame within said cage; and

an upwardly extending lip extending along a side of said frame.

2. The feeder assembly of claim 1, wherein said frame has at least a second support descending from said frame.

3. The feeder assembly of claim 1, wherein said at least one support forms a polygon.

4. The feeder assembly of claim 1, wherein said feeder assembly is constructed of transparent plastic.

5. The feeder assembly of claim 1, wherein said feeder assembly is constructed of plastic, said at least one support having sides, the sides being radiused to prevent gnawing by an animal.

6. The feeder assembly of claim 1, wherein said first and second flanges support said frame.

7. The feeder assembly of claim 1, wherein said at least one support supports a water bottle therein, said at least one support descending from said frame at a substantially right angle.

8. A feeder assembly for use in an animal cage, comprising:

a frame;

at least one support descending from said frame; and

a pair of flanges extending from said frame to support said frame within said cage, said at least one support has an open lower end and further comprising a snap on bottom, said snap bottom being selectively connected to said lower end of said at least one support.

9. A feeder assembly of claim 8, wherein said snap on bottom has an upper lip extending there around, and having a channel extending around said lower end, said upper lip receiving said channel to connect said snap on bottom to said at least one support.

10. The feeder assembly of claim 9, wherein said upper lip has a recess and said lower end has a tab, being received by said recess for locking said snap on bottom to said at least one support.

11. The feeder assembly of claim 8, wherein said snap on bottom is a food container.

12. The feeder assembly of claim 8, wherein said snap on bottom is a water bottle support.

13. The feeder assembly of claim 12, wherein said snap-on bottom has an opening therein.

14. The feeder assembly of claim, 8, wherein said snap on bottom forms a flush surface with said at least one support.
