The Catit PIXI Cat Fountain Filter Cartridge is a replacement filter for Catit's PIXI drinking fountain range, sold in a pack of three. It fits all PIXI fountain models directly, covering several months of regular maintenance without needing to source compatible third-party alternatives.

Filtration works in multiple stages: a mesh layer catches visible debris and hair, while the filter medium removes odours, impurities, and heavy metals from tap water. The process also softens the water, which most cats find more palatable — a detail worth noting for cats that ignore their bowl in favour of the tap. Monthly replacement is the recommended interval to maintain consistent filtration performance.

Cats that favour running water over a static bowl tend to drink more consistently from a fountain — but only when the water tastes clean. Regular filter replacement is what keeps that preference working in the owner's favour rather than creating another thing the cat decides to boycott.
