Our cat is drinking from the fountain, we have a lot more than ever before, and wants since then have no standing water more. It is Freigängerin, but comes to booze in the house and makes more recently even a detour around our pond. Cleaning is a bit awkward and you have to watch that one strikes with the not quite lightweight ceramic nowhere, otherwise they may quickly go to break, but the stated objective: "cat needs to drink more, so that they will get no problems with the kidneys" was clearly achieved. A 100% guarantee there is not. Kater example ignores the fountain and booze rather be out. For such cases, the manufacturer even offers a redemption. We reserve the wells because of our cat. The stubborn hangover must see that he quenches his thirst at another location then stop.
Addendum 13.03.2015: He's just out of the slow variety, our cat, but now he has discovered the fountain itself and comes as the cat to drink water separately into the house, rather than to use the outdoor pools. Experiment a complete success.
