You can jump to the fountain info: 3:40
Last year I got some betta fish. Katie, one of my cats took a special interest in the fish. I found her sitting by the jar I had the fish in giving a good look over. I thought that if I gave the cats their own water feature, they would be less interested in the aquariums.
The fountains for pets can be pretty pricey, so I searched around for a DIY alternative. The common denominator for the DIY fountains was the use of an aquarium pump or filter.
You basically need an aquarium pump or filter and a large bowl to give your cats a fantastic moving water fountain.
