I love my new Drinkwell one gallon pet water fountain! Before I started using it, I was filling two water bowls daily for my dog and cat. With this fountain, I just open the top and pour my gallon of water in! It’s so much easier and time saving. Both my dog and cat drink from it, so I don’t have to keep water bowls sitting out anymore! They have different sizes to choose from and I highly recommend this product for any pet owner!
