This stainless steel cat water fountain has a large 135-ounce (approx. 4L) capacity. It features a water level viewing window, allowing you to see the remaining water at a glance. This automatic water dispenser can be used for both cats and dogs, and is designed with multiple water outlets for easy access. It uses an ultra-quiet pump, so you can use it without worrying about noise. The size is approximately 12cm (4.724 inches) in height and approximately 24.5cm (9.645 inches) in diameter. A plug is not included, so you will need to prepare one separately. This water fountain is a convenient item for providing your pet with fresh water at all times. Thank you for viewing.
