received within the upper end 58 of sink 50 for supporting an animal directly over the reservoir 56 of the sink 50 in the embodiment shown a ledge 92 extends around the inner periphery of the sink 50 near the upper end 58 for supporting the grille 90 thereon the grille 90 comprises outer peripheral frame members 94 and a plurality of spaced transverse rods 96 extending between the frame members 94 for supporting an animal thereon the grille 90 may further include one or more longitudinal rods 98 extending between the first and second ends 32 34 of the animal support assembly 30 to help strengthen the grille 90 because the transverse rods 96 are spaced apart fluid material from the animal or fluids used during treatment may flow between the rods 96 and into the reservoir 56 the fluid material is then directed along bottom wall 52 to drain 60 whereafter it is removed from sink 50 through conduit 64 in use the animal support assembly 30 may be moved to a position close to the floor surface to facilitate placing an animal onto the veterinary procedure table 10 the animal support assembly 30 may thereafter be raised vertically upward to any height desired by the practitioner the weight of the animal supported on the grille 90 is transferred to the load cells 70 the static weight of the sink and grille having been zeroed out as described below the control 84 receives signals from the load cells 70 and calculates the weight of the animal the control 84 then sends signals to the display 88 to.
