<p>A drinking trough for small animals comprises a bowl (1) in which the liquid is maintained at constant level by supply from a container (2) which receives an inverted bottle (4). The container is extended upwards by a sleeve (9) to support the bottle. The sleeve is cut away at the side nearer the bowl. The bowl is disposed inside a cage, and the trough engages an opening in the cage wall. The supply opening (6) in the partition (5) permits liquid to pass into the bowl. The bottom of the container is formed as a funnel to ensure flow of liquid from the bottle.</p> |
