We love this water fountain! Set up was very simple. The water bowl area is the perfect shape and size so that whiskers are not disturbed while drinking. Cats are more drawn to moving water rather than stagnant and I think mentally it’s a plus for them as well. It’s more natural, like having your own spring water source. I noticed that it took our cat a few hours after set up to trust the new fountain. Once he gave it a try he sat there for so long! Taking a few drinks, watching the water, and just seeming to enjoy himself and his new fountain!
