Adequate and clean water intake is very important for your cat’s overall health. This ultra-quiet automatic cat water fountain encourages your little feline to drink more because cats are instinctively attracted to moving water. With no bowl for the water to pool in and a superior filter, this fountain keeps dirt, debris and other nasties out of your kitty's water. Features: The river inspired the drinking fountain's design. Our filter system balances the PH value and purifies the water quality. Our circulation filtration system effectively filters floating impurities and ensures clean drinking water. The fountain is simple to assemble and disassemble for cleaning, so there's less hassle for you and more irresistibly clean water for your baby. Made of BPA-free materials to be extra-safe and non-toxic for your kitties and puppies. Dimensions: 6.7 x 9.1 in (23 x 16 x 13cm) Water Fountain Filter Replacement - 4packs (Included) Recommend: Replace the filter every 15-30 days.
