Extra large capacity: This water fountain for cats and dogs has a capacity of up to 3 liters, allowing your pet to enjoy fresh, clean water for up to 12 days. This reduces the need for frequent refills and thus saves water. Triple filtration: Our water fountain is equipped with a filtration system consisting of non-woven fabric, ion exchange resin, and activated carbon. This system removes waste, impurities, and heavy metals, ensuring your pet maintains healthy hydration and kidney health. Silent motor: Our water fountain's motor uses new technology, making it much quieter than other water fountains (only 20 decibels). Therefore, your pet will not be scared. You can leave the water fountain on day and night without it affecting your rest or daily activities. Low energy consumption: The 5V water pump ensures stable water circulation and low energy consumption, making it an environmentally friendly, durable, and economical pet product.
