The Catit PIXI Fountain Filter 3 Pack ensures your cat always has access to fresh, clean, and great-tasting water. Designed for use with the Catit PIXI drinking fountains, these triple-action filters remove impurities, chlorine, and odours, while also softening hard tap water to prevent urinary tract issues. The multi-layer filtration system helps capture hair, dirt, and debris, keeping the water pure and reducing limescale build-up. Regular filter changes promote better hydration and improved kidney health for your pet.
