The Catit LED Flower Fountain's compact 3 L (100 fl oz) water reservoir was designed to take up little floor space. The features include an LED light, which makes the fountain light up at night, and a handy water level indicator so that your cat's water will never run low. The unique petal top feature pours water into the six pockets, allowing your cat to drink even when the fountain is turned off. The Catit Flower Fountain LED allows up to 3 different water flow settings to appeal to picky drinkers! Cat owners can switch between gently flowing water, faucet-like streams of water, or streams of water with a bubbling top. The fountain provides clean, cool water at all times by pushing only filtered, running water to the surface. It is easy to disassemble and clean and has an ergonomic design which helps prevent whisker stress and feline acne. It includes a triple action filter, which helps prevent urinary tract diseases. Additional replacement filters are available separately in a pack of 2 (43745) or a pack of 5 (43746).
