Everyone here loves pet drinking fountains, but some designs could do with a bit more style, which is why the new Drinkwell Lotus Pet Fountain from Radio Systems Corp. received all thumbs and paws up from our testers. It has style in waves. The multi-level drinking fountain holds 50 ounces of water and uses a foam filter to help remove particles and hair from the water, the company reports. The innovative design features water that bubbles up into the top dish and spills out into the bottom dish through three free-falling streams. In addition, the fountain dishes are constructed using ceramic material, which can help prevent the condition known as feline acne, the company adds.
