The Cat Mate 2 Litre Pet Water Fountain provides three height levels for your pet to choose from, ensuring plenty of water movement for naturally oxygenated, tasty water. It includes a polymer-carbon filter to help provide a healthy dose of H2O throughout the day, as well as keeping the water clear of dirt and fur. This multi-height pet water fountain from Cat Mate is suitable for cats of all sizes and even smaller dogs. The constantly-flowing water is a great way to encourage your pet to drink more. The fountain has been designed with a tiered system that offers your pet different drinking heights. As the water runs from the top level to the lower bowl, it acts as a waterfall, while reducing splashing water and keeping the area around your pet's drinking fountain dry. It is particularly safe and has a quiet operating sound, as well as being easy to keep clean as the bowls can be removed and put in the dishwasher. The fountain is made from easy clean, dishwasher safe bowls and comprises a noiseless operation system and in-built carbon filter to purify water continually, keeping it fresh, cool and filtered. The pump has a power consumption of 2W and operates at 230 - 240 V. It is recommended to change the water in the fountain weekly and descale the fountain monthly. Replacement filters and pumps are available separately.
