We both work and have two cats. It's good to know that we have them taken care of during the day in regards to food and water. The watering system is nearly perfect except being able to clean the inside of the water container. After constant use "schmootz" tends to build up where the water sits when the jug is inverted. I haven't been able to find an adequate brush to reach into that area. So I'm going to get a replacement system and have decided my little furry friends deserve purified water to help eliminate particle build up. The mfg may want to consider offering replacement jugs on their own. But a good product, sturdy and convenient.
