Keeps water circulating Charcoal filter absorbs tastes and odors Adjustable flow control for gentle cascade 6-cup water capacity, expandable to 12 cups Easy to carry Does your pet turn her nose up at her water after it's been standing for several hours? Make your pet's water more appetizing and encourage her to drink more with the Pet Drinking Fountain! This veterinarian-designed "drinking fountain" continuously circulates and filters your pet's water, making it more appealing than standing bowl water. The flowing action breaks the surface tension of the bowl water to draw in oxygen from the air and aerate the water, keeping it fresher-tasting. Fresher-tasting water encourages water intake and proper hydration, which helps maintain a pet's health. If you have a cat that likes to jump on counters in search of dripping faucets, this fountain can help stop counter-jumping by satisfying the cat's need for running water. The fountain pumps the water through a charcoal filter, which absorbs tastes and odors. A pitcher-like spout stands 5" above the floor, creating a long waterfall. The flow control is adjustable, allowing for a gentle cascade, while a grate over the opening prevents kibble from blocking the water flow. The Pet Drinking Fountain is made of safe ABS plastic with convenient side carrying handles, and completely disassembles for regular cleaning. Simply fill this self-contained fountain with water, plug it into a standard indoor outlet with the included 6' cord, and it is ready to be used. The fountain holds 6 cups of water for your pet; double the capacity to accommodate multiple pets or increase the time between refilling by adding an easy-to-attach, optional 6-cup water reservoir.
