Premier Pet Fountain works great. My cats love the flowing water and it comes out at 4 spots plus the dish is nice and big with room for them to drink from either spot.   It holds 128oz of water.  I love that you can adjust the flow with a knob. It is constantly flowing and keep the water fresh. It has 2 filters - one removes dirt and hair and the other keeps the water fresh with the carbon filter. It is low voltage so safe and cheap to use. It BPA free making it safe for my cats. I love that you can put it in the dishwasher top shelf. Premier Pet is a great company and this is a quality product
