Pros:All cats love it!(5 personal cats & about 12 cats who have been fostered here during the ~ 10 months we've had it.)Cons:Cumebersome & difficult to clean. Requires frequent cleaning. No way to mechanically clean (wipe/scrub) most of tank.About 1 month after I got it, negative feedback mechanism that prevents all water from running out of tank immediately after filling stopped working. When tank filled, water runs out into bowl & keeps running out until tank empty resulting in water overflowing bowl & onto floor. Thus extra large tank to hold extra water for more cats useless.LOUD. VERY LOUD.I CANNOT recommend this product.I can only hope it dies quickly as others have so that I can get a different one without feeling guilty.
