I like that it is high ounceage, easy to clean, easy to fill. Our dog Bella loved it before we had to put her down, and our cat Thor loves it too. It's high enough for a dog, but not too high for a cat. Highly recommend!great product and very beneficial to my catFits the fountain, lasts about a weekWorks greattMy cat always wanted a drink from the bathroom sink. He NEVER drank from his bowl. I got the fountain and it took him a few days to try it. But now he uses it all the time and doesn't beg for sink water very often. I occasionally toss an ice cube on the top and he likes that too.They work as expectedEasy to use & easy to cleanSuper bueno
