Ultra Quiet Water Pump - This cat water fountain features an ultra-quiet pump that operates at less than 30 decibels, providing a near-silent environment for both you and your pet. The fountain is constructed from premium 304 stainless steel, which is BPA-free and offers greater durability compared to plastic or ceramic alternatives. Large Capacity - With a 3.2-liter (108-ounce) capacity, this pet water fountain reduces the need for frequent refills. It can support a cat's hydration needs for up to 14 days and a dog's for up to 9 days, making it ideal for short trips or daily use without constant supervision. Built-In LED Light - The fountain includes a built-in LED light that illuminates the water chamber, allowing easy water level monitoring through the transparent housing. The light also glows in low-light conditions, helping pets locate the fountain at night. Circulating Filtration System - Equipped with an activated carbon filter containing cotton, coconut shell activated carbon, and ion exchange resin, this fountain effectively removes odors, softens water, and captures impurities and pet hair. Combined with the sponge filter on the pump, it ensures a clean and healthy water supply. For optimal performance, replace the carbon filter every 2 to 4 weeks. Two Flow Modes - This cat water fountain offers two water flow options: a dual outlet faucet mode and a fountain mode. Designed to mimic natural running water, it encourages pets to drink more by increasing water aeration and freshness. The flowing water feature supports kidney health and is suitable for homes with one or multiple pets.
