With instructions Includes 3 replacement filters (new and unused) ★Please understand that this has been stored at home before purchasing. ■Size/Capacity [Product Name]: Automatic Water Dispenser [Size]: Approx. W175XD175XH155mm [Quality Indication]: 304 Stainless Steel [Target]: Cats, Small to Medium Dogs ■Product Introduction [SUS304 Stainless Steel & Hygienic and Highly Durable] The pet water dispenser uses SUS304 food-grade stainless steel, which is resistant to wear and tear and lasts a long time. Plastic water dispensers can get bite marks and gaps, which can lead to the breeding of bacteria and affect the health of your pet's drinking water. [2L Large Capacity & Ideal for Multiple Pets] The cat water fountain has a large 2L water storage capacity, so you don't have to worry about your cat's drinking water when you are away for work or a short trip. In addition, a wide water area increases the contact area between water and air, which has the effect of supplying oxygen to the water and making the water taste better. It does not affect multiple cats drinking at the same time. [Quiet Pump & No Interference with Sleep] Equipped with a low-pressure, ultra-quiet pump of less than 20dB, this water dispenser allows both pets and owners to sleep without worrying about noise at night. There are four suction cups under the pump to keep it in close contact with the water tank, preventing the pump from floating and further reducing noise. [Easy to Clean & Easy to Install] Made of stainless steel, the smooth surface makes it difficult for bacteria to hide, and it is easy to clean.
