We had a water dish for the dogs in the kitchen and one in the cat room for the cats. The last few times the cat's water dish was knocked off the shelf and spilled all the water on the floor.

We now use just one for all the animals. It stays in the kitchen, and we have to be sure its filled often, because if it gets low on water one of the cats knocks it over. We are not sure who, but we are thinking its Ashton knocking it over
