Keeping up on water bowls in these our busy times is challenging.  Often times I have found the water bowl empty. This pet fountain enables a large amount of water (1 gallon!) to not sit stagnant.  With the adjustable flowing feature, water appears to stay fresher longer. Great for use with many differnt animals.  We use it for our indoor cats and free range ferret.  Some assembly is required, but not difficult to set up using the instructions included.  Dark grey color is rather generic in nature, but tends to compliment its surroundings. When water is low, the pump makes a loud sound audible from a distance to alert you when to add more should you overlook refilling it.  Helpful addition to your animal care.
