The RIZZARI Automatic 3L Pet Waterer is designed mainly for cats and small to medium-sized dogs, offering a generous 3-liter capacity that can keep your pet hydrated for a full day or more. Its gravity-fed system refills water slowly, which means less frequent refills—great if you’re busy or away from home for a while. Made from BPA-free, food-grade polypropylene, it is safe and durable, though it does not include a stainless steel bowl, which some pet owners may prefer for hygiene reasons. The transparent body makes it easy to see when water levels are low, so you won’t be caught off-guard, and the split design allows for straightforward cleaning of all parts, helping maintain freshness without hassle. The base has a raised, non-slip design that helps avoid spills or leaks, even if your pet nudges it.
