- Why choose a flowing water source Cats prefer flowing water to static water. The faucet shape satisfies a cat's curiosity and exploratory nature, while the circulating water helps keep it cleaner over time. Use this cat water fountain to provide your pet with access to flowing water, encouraging regular drinking. - Big Eyes water level display A clear display window lets you check the remaining water at a glance. There is no need to tediously open the lid, which saves time compared with ordinary stainless steel cat fountains. - SUS304, healthy food-grade material The fountain is made of high quality stainless steel SUS304 imported from Germany, resistant to high temperature, corrosion and oxidation, reflecting quality and safety. Compared with plastic materials, it helps reduce the risk of a black chin in cats. Note: the water level window is not stainless steel and cannot be used in a sterilizer. - 108oz / 3.2L capacity, 8 days of drinking water The capacity is 3.2L, enough to meet the drinking water needs of an adult cat for about 8 days. For short trips, your pet can still have access to fresh domestic water daily. The fountain reduces refilling frequency—fill once and enjoy convenience. - Multiple filtration, healthier The filter system uses high-density filter cotton, activated carbon from coconut shell, and ion exchange resin cartridges, plus pre-filter sponges on the pump. This multi-stage filtration intercepts hair and fine debris, softens hard water, and removes invisible particles, helping to provide healthier water for your pet.
