I love these bowls. They look great and the slow feeder has really lengthened the time my little one takes to eat her food.
I helps him to slow down when eating and also stimulates him mentally. It looks very elegant, fit for a King and my Happi is a Royal Being. The only negative is that the outside has a beautiful matte finish which while elegant, is difficult to clean when coated with all of Happi's slobber.
Love the colors that we got - blue for water bowl and slate for food bowl. We were tired of unaesthetic pet supplies, and these are both functional and beautiful!
