The flower fountain uses running water to encourage your animal to drink more. Regular drinking is important for your cat's health, as it helps ensure proper kidney function and prevents the formation of crystals that can lead to urinary tract diseases. The Catit flower fountain includes a dual-action filter to soften the water (refill packs are available separately). The filter continuously purifies and softens hard tap water, while also retaining stray hair, sediment, and debris. The Catit flower fountain is easy to disassemble and clean. Simply wash each part by hand using natural soap, free of chemicals or abrasive solutions, and rinse thoroughly.
