## Abstract

Systems and methods directed to small animal containment and/or breeding include a container top having a vent and a feeding chute. The vent is a plurality of similarly sized holes or a void configured to receive and/or be covered by an exchangeable vent plate or cover. The feeding chute preferably provides a cradle to receive food that can be accessed by a contained animal through the thickness of the chute. A water aperture through the container top is configured to receive a ball bearing sipping tube which is operatively coupled to a water supply implement, but a chew shield is preferably formed integrally as part of the container top to prevent access to through the container top to the water supply implement. Hollow, single-end capped tubes may be provided to extend through one or more apertures formed through the top to allow for small animal or insect extraction.

## Claims

### Claim 1

A container top comprising:
a top surface extending between and including a plurality of edge portions;
a bottom surface opposite the top surface, the bottom surface configured to mate with a majority of a lip of a container;
a vent formed through the top surface, the vent configured to allow air exchange through the top surface;
a chute extending downward from the bottom surface, the chute comprising a pair of planar panels meeting at a chute base bend;
along each of the plurality of edge portions, a registration flap depending downward from the bottom surface;
a first plurality of apertures formed through one panel of the chute; and
a plurality of tubes, each tube extending through one of the first plurality of apertures, wherein each tube comprises a closed end and an open end disposed on opposite sides of the one panel.

### Claim 2 (depends on 1)

The container top according to claim 1, the top comprising a unitary piece of material.

### Claim 3 (depends on 1)

The container top according to claim 1, the vent comprising a second plurality of apertures formed through the top surface.

### Claim 4 (depends on 1)

The container top according to claim 1, the top surface comprising a substantially planar surface.

### Claim 5 (depends on 3)

The container top according to claim 3, the top formed by a process comprising:
providing a sheet of stainless steel;
working the sheet of stainless steel to form an outline, the first plurality of apertures, and the second plurality of apertures, the working comprising at least one of stamping and laser cutting;
bending the sheet of stainless steel to form the registration flap; and
bending the sheet of stainless steel to form the chute.
