Our pets love this fountain. It is great at keeping their water clean and fresh. We leave our cat home for a couple days at a time and this works well for keeping her in water. It holds 81oz and that will last her days. It is well made and very quiet, when the water get really low then it does make a little bit of noise but not bad.. The water can be adjusted to 3 modes: flower waterfall, flower bubble, and gentle fountain. The only thing I think would make it better is if it has a battery backup in case the power goes out.
