Keep pets hydrated with the Zeus H2EAU Cascade fountain for dogs, a high-capacity 6 L dog water fountain ideal for large breeds, older dogs, or pets with joint or muscle issues. Its re-circulating water flow cools and aerates water to eliminate stagnant water. A large water-to-surface area adds oxygen for fresher, tastier water that pets love. The replaceable foam/carbon filter collects food, hair, and debris while helping reduce bad tastes, odors, and absorb impurities present in tap water. Includes a detachable AC adaptor and is also suitable as a cat water fountain.
