My cats love this! Ever notice how your cat will come investigate when you’re pouring water into his bowl? Turns out cats are drawn to the sound of trickling water! It’s not loud…just a barely audible trickle…but they really like it. I thought it would be useful for when the family goes away and we need to leave a couple days worth of water, but I’m actually using it as their everyday water bowl now! The fountain itself is very easy to set up and use. Add water every couple days by pouring it right in through the top. It just needs to be emptied and rinsed out every week or so.
