Cat drinking fountain water filters

These are cat drinking fountain filters that are compatible with most fountains and designed to keep your cat's water clean and fresh. I switched to a different fountain type. They are new, never used. Package of 9. These filters are an essential item for your cat drinking fountain. Grab them before they're gone! They're probably thinking, 'If the ad is still up, the filters are still available, right?' Well, your cat's intuition is spot on!
