I suspect that the animals do not drink water which human would not be able to drink. After drinking contaminated water, they suffer the same as people. Maybe it would be better amenity=drinking_water+watering_place=yes/no or amenity=fountain+watering_place=yes/no ect:. or alone watering_place=yes/no
watering_place=no if it is forbidden to watering animals.
