I needed a drinking fountain for my kittens who recently turned six months old and I wanted one that wasn’t too large so they wouldn’t  be intimidated by it. The pogoda style Himalaya fountain hit the mark for what I was looking for. They can drink out of the bottom and also they are learning to drink on the side where the water flows out. The only thing I don’t like is it uses two separate filters so that’s an added expense but everything else about the fountain is great and the cats love it.
