We have both dogs and cats in our house. The cats are finicky about their water and the dogs would drink out of any water bowl in the house. After the dogs had finished drinking, the cats didn't want anything to do with the water in the bowl. This self filtering bowl is a solution that keeps all of them with fresh clean water with minimal fuss.
The bonus is that this filtering water bowl is about half the price of some of the commercial filtering water bowls and will hold at least two gallons of water.
