Flower Fountain 3L Drinking Fountain with Triple-Action Filter. Encourage your cat to drink more. Drinking regularly is important for your cat’s health as it helps ensure proper kidney function and helps prevent crystal formation that can lead to urinary tract diseases. 3 water flow settings for picky drinkers! Since cats are picky drinkers, Catit developed the Flower Fountain to feature 3 different settings: a gentle water flow, a bubbling top, or calm streams. Clean water at all times, unlike bowls, the Catit Flower Fountain pushes only filtered, running water to the surface. This prevents your cat from having access to dirty water. Includes Triple Action Filter to help prevent urinary tract diseases. The Catit Triple Action filter removes magnesium and calcium from tap water. These minerals can accumulate in your pet’s lower urinary tract and lead to urinary tract diseases, which is a common health issue for cats. Removes odours caused by bacteria and chlorine, and retains stray hairs, sediment and debris.
