Query: Clicking

Even though my cats were afraid of it at first it works rather well. Unfortunately if it isn't filled all the way, the water reserve fogs and looks unkept. Also when it's not completely full it produces this annoying clicking sound. It has a very small reserve and needs to be refilled often so the clicking can get to be constant. Other than that, it's very nice looking and matches with the stainless items in my kitchen.
