In one embodiment, a watering assembly includes a basin and a bowl disposed on opposite sides of a cage wall. The basin and the bowl are releasably coupled to one another, for example by a hook-socket combination. The basin includes a pump that moves water along a supply conduit and into the bowl. The bowl has a return conduit that returns water from the bowl to the basin. A reservoir is coupled to and in fluid communication with the basin so that watering assembly may provide a volume of water that is greater than the combined water-holding volume of the bowl and the basin.
