【Ultrasonic Water Pump】- Equipped with an ultrasonic water pump that operates at a sound level below 30 decibels, our cat water fountain is almost silent. It provides a quiet sleeping environment for you and your pet for a good night's sleep. In addition, the cat fountain is made of premium 304 stainless steel, which is BPA-free, healthier, and more durable than plastic or ceramic counterparts. 【Large Capacity】- Our pet water fountain has a large capacity of 108oz/3.2L, which means you don't need to refill water frequently. It meets a cat's drinking water needs for 14 days and a dog's for 9 days. You don't have to worry about your pet when you are away or traveling, our cat fountain can still provide your pet with enough clean drinking water. You can go to work or travel with confidence! 【Built-in LED Light】- The stainless steel cat water fountain is designed with a built-in LED light. It is convenient for you to observe the water level through the transparent fountain wall at any time, you don't need to open the dog water dispenser frequently. At the same time, the built-in LED light can glow in the dark, so your cat can find the cat fountain faster. 【Circulating Filtration System】- The cat water fountain is equipped with an activated carbon filter, which consists of cotton, activated coconut shell, and ion exchange resin. Together with the sponge filter on the pump, our cat fountain can not only effectively soften the water and remove odors, but also filter out most impurities and trap hair, providing your pet with a clean and healthy water source. It is best to change the carbon filter every 2-4 weeks for your pet's safety. 【2 Different Flow Designs】- The cat water fountain has 2 water flow modes: double outlet faucet mode and fountain mode. It is perfect for a family with one or more pets. Our pet water fountain simulates the sound of water flowing from faucets and fountains. A spring with running water oxygenates the water to increase oxygen content and freshness. It not only encourages cats to drink more water instead of stagnant water, but also has a beneficial effect on your pet's kidney health.
