Pet water fountains are devices designed to provide a continuous flow of fresh water for pets, such as dogs and cats. They typically feature a reservoir that holds water and a pump that circulates it, creating a gentle stream. This movement helps to keep the water oxygenated and can encourage pets to drink more, promoting better hydration. These fountains come in various sizes and styles, often made from materials like plastic or stainless steel. Many models include filters to remove impurities and improve water quality. Overall, pet water fountains can be a convenient and beneficial addition to a pet owner's home.
