My two dogs and 8 cats all share the same large water bowl. Some of my cats stick their paw in and some don't. I think they are just trying to move it around so they can see it or they are moving it to smell and make sure it is fresh. My cats love fresh water. I fill the large bowl every morning and they all come running as if the half bowl of water that was there from the morning before was rotten and they are dying of thirst
