The Penthouse Paws Smart Wireless Dog & Cat Water Fountain provides your pet with fresh, filtered water for the ultimate hydration experience. This top-of-the-line, smart, wireless water fountain has a 3.5 liter capacity and combines sleek design with cutting-edge technology. The advanced hollow fiber ultrafiltration system continuously removes dirt, fur, and heavy metals. A special cleaning cycle utilizes UV light to further purify the water tank for optimal hygiene. Plus, you can use WiFi to seamlessly connect the fountain to the free Penthouse Paws app on your phone for convenient control and monitoring. The smart app alerts you when it’s time to refill the water tank, clean the fountain, replace the filter, or recharge the battery. The lithium-ion battery pack provides up to 45 days of use on a single charge—eliminating the need for messy cables and allowing you to place the fountain anywhere in your home. Plus, the fountain is whisper quiet, running at just 23 decibels. It’s equipped with filter- and battery-saving Smart Sense Mode, which automatically detects when your pal approaches and only then activates water flow. The continuous flow of fresh water encourages your fur-iend to drink more— promoting optimal hydration and helping prevent common illnesses like urinary tract infections and kidney failure—so your pet stays happy and healthy.
