The Petmate Auto-Feeding System provides pets with a continuous supply of food throughout the day. - http://www.petco.com/shop/searchresults.aspx?Ntt=Le%20Bistro%20Feeder&N=30%20231&cmref=Brand&cmrefv
The Petmate Le Bistro provides your pet with access to food any time he, or she, needs it. It's very easy to fill up the unit. You just, simply, take off the lid, pour the food on the top, and gravity takes care of the rest, bringing the food down into the bowl as your pet eats it. The bottles are made with microban, which is an anti-bacterial that fights bacteria to keep the bowl and the bottle, cleaner. So it's great for indoor or outdoor use.
