Bergan's gourmet waterer will keep the liquids coming, even when you’re not home, automatically dispensing up to 1.5 gallons of water. There is a matching feeder, but it gets such disappointing reviews that we skipped it. However, we like the styling so much, we're are carrying the waterer anyway, since so many people are happy using a waterer and feeding by hand. Maybe we'll add the feeder if they resolve the 'food clogging' issue! Dimensions are roughly 11 x 11" with a 12" projection.
