Parner Pet Water Fountain, Automatic Cat Water Dispenser, Pet Supplies, 2.5L Large Capacity, BPA-Free, with Water Level Indicator, LED Light, 4 Activated Carbon Filters, Silicone Pad, for Cats, Dogs, Birds, and Other Pets I am selling this because I upgraded to a higher-end model. I bought this because of its large capacity and the double filtration with sponge and filter. I will include one filter so you can use it right away. #HalloweenOnMercari
