The tank includes a float valve for controlling the supply of water from the tank to the drinking tray. The tank is shaped so as to be nestable with another tank and includes a first pair of nesting members formed on the first sidewall of the tank, and a second pair of nesting members formed on the second sidewall of the tank, and the first and second pairs of nesting members each having nesting surfaces on their lower edges for engaging and resting on the upper rim wall of another tank in order to allow the tank to nest within another tank and to space the tops of the tanks apart a predetermined amount. The upper rim wall of the tank has a first U-shaped channel extending between the first pair of nesting members, and a second U-shaped channel extending between the second pair of nesting members. The first and second U-shaped channels having therein first and second longitudinal support members extending between the first and second pairs of nesting members, respectively, and each being adjacent to the first and second sidewalls of the tank, respectively, in order to provide increased structural integrity and nestability of the tank when nesting two or more of the tanks with each other.
