The Catit Flower Fountain uses running water to encourage your pet to drink more. Drinking regularly is important for your cats health, as it helps ensure proper kidney function and prevents crystal formation that can lead to urinary diseases. The Catit Flower Fountain pushes only filtered, running water to the surface, to encourage your cat to drink more. The Catit Flower Fountain can be set to a gentle water flow, bubbling top or calm streams so will appeal to even the pickiest of drinkers. The catit flower fountain includes a dual-action water softening filter (refill sets available separately). The filter continuously purifies and softens hard tap water, while also retaining stray hairs, sediment and debris. Suitable for small to medium sized cat and small dog. Green. Plastic. H18.5, W21, D21cm.
