My cats love the fountain and drink more water now. The owners of the company go above and beyond in customer service. Initially I purchased a fountain with a tall centerpiece. My cats started knocking it over. They let me buy a lower center. I accidentally cracked the pump cover and they sent a new one. When the pump wore out, they sold me a new one and helped me to install it when I had trouble following the printed directions. If only all merchants were like this.
