I set this up for my three dogs thinking that they would get a kick out of it. Well. All three of them ended up absolutely loving to drink out of this over our other water bowl. I feel good that they can have a cool fresh drink of water anytime they want. What really surprised me is that my cats are also into it. What a great product. I found it easy to assemble. Just make sure you follow the directions to a t as this will prolong the life of the fountain and your filter. I've seen these pet water fountains before, but they are usually smaller and marketed towards cats. I'm delighted to find one that's bigger and suitable for both cats and dogs at the same time.
