Fountain provides your pet with 2.5L of fresh, filter water. The dual-filtration system includes an activated carbon filter, to remove bad tastes and odors, and a foam filter, to remove dirt and hair. Flowing water encourage pets to drink more, therefore supporting urinary and kidney health through proper hydration. The constant flowing water, which can be adjusted with a flow control knob, helps to prevent bacteria growth, keeping the fountain cleaner than a standing water bowl. The new sleek, compact designer offers your pet multiple drinking options: four free-flowing streams or the lower bowl with still water. This BPA-Free plastic fountain comes apart for easy cleaning .
