I’ve had my Thirsty Cat fountain for five years. I’ve always loved how pretty it is, and the calming water sounds it makes, too. It still works as perfectly as the day I got it, and is still a breeze to clean. My cats aren’t picky about where they drink water from, and will happily drink from the fountain, or a regular water bowl. However, my dog absolutely loves it. The fountain is her preferred water source. I have to clean it a little more often because of this, but I can attest to the filtration system and pump being able to process and withstand even dog levels of backwash. Really great product, I recommend it to everyone.
