The present invention pertains to a system for preventing hyperthermia in minks (400) kept in cages (10, 11, 12, 13) comprising a semi-continuous row (5, 6) of separate cages (10, 11, 12, 13), each cage being provided on the inside with an open container (20, 21, 22) for keeping water, the opening of the container corresponding to a size of the head of a mink (400) to be kept in the cage, a water duct (30) running along the row of cages, a unit (35) for providing water in the duct at a pressure above atmospheric pressure, at each open container a conduit (31, 32, 33) for providing a fluid connection between the interior of the water duct (30) and the interior of the open container (20, 21, 22),each conduit being provided with a valve (50) that can take a first position wherein the fluid connection is blocked, and a second position wherein the fluid connection is established, wherein the valve is actuable to change between the first and second position using a predetermined actuating signal. The invention also pertains to a method of using this system.
