Say goodbye to frequent filter changes and extra costs.TIPS: The black sponge is used to prevent pipeline blockage.

On Mode 2, it lasts more than 15 days on a single charge—great for emergencies or spots with shaky power. If the electricity cuts out, it seamlessly switches to battery mode so your cat stays hydrated.
  • 3L CAPACITY FOR WORRY-FREE TRAVEL ☛ With a generous 3L clean water tank, this smart cat water dispenser keeps your pet hydrated for 3–9 days. Perfect for when you’re home or away—fewer refills, more peace of mind.And made of food-grade materials, with all water-contact parts BPA-free.

  • CLEANING IS A BREEZE ☛ Cleaning is simple: rinse the tanks and stainless steel tray with soap and water, and wipe down the main unit with a damp cloth (note: the main unit isn’t washable).
