This is an automatic water dispenser purchased for my cat. I actually used it for about a week, and only used the filter once before I stopped using it. I'd like to pass it on to someone who has a cat that's often left alone. I bought it for 5980 yen. ✼••┈┈┈┈┈┈┈┈┈┈┈┈┈┈••✼ Uchino-ko Electric / Plus Aqua - +AQUA - Aqua Mebius Next Generation Model Cat Dog Water Dispenser Automatic Water Dispenser 2l Ultra-Quiet Japanese Manufacturer's 1-Year Warranty Support with Activated Carbon Filter Cat Water Product Name: Plus Aqua / Uchino-ko Electric Circulation Water Purifier Water Dispenser Tank Capacity: 2 liters Power Supply: Included AC adapter (AC100-240V: 50/60HZ) Metal cord for bite-through protection *This product is designed to prevent the danger of chewing through the power cord, but does not guarantee 100% safety.
