The Premier Pet Fountain provides your pet with 60 ounces of fresh, filter water. The submersible pump circulates the water through two filtration systems: a foam filter, to remove dirt and hair, and an activated carbon filter, to remove bad taste and odor. Cleaning the fountain and replacing both filters at least once a month ensures the freshest water and a longlasting fountain. The BPAfree plastic design comes apart for easy cleaning and it is topshelf dishwasher safe. (excluding the pump.) This updated design continuously moves water to prevent bacteria growth, keeping the fountain cleaner than a standing water bowl, and encourages your pet to drink more. Your pet will have the option to drink from four freefalling streams or the shallow bowl. By drinking more, your cat or dog will stay properly hydrated, promoting a healthier lifestyle and happier pet.
