The automatic pet feeder allows you to set up to 6 feeding schedules and is compatible with dry food ranging from 2-15mm in size. - Color: White - Feeding Schedule: 6 times/day Thank you for viewing! This is a 3-liter automatic pet feeder. I bought it for my cat who would want food in the middle of the night or at 4 am, and it was a great help. It was convenient because I could freely set the feeding times to match my cat's eating pace, and I could also adjust the amount of food dispensed at once. The power source is not only from a power outlet, but also uses batteries in case of a power outage, so it's safe. Overall, there are no scratches or stains, but the stainless steel container in image 12 has some slight cloudiness, showing signs of use. Please take a close look at the images before considering a purchase. I will also include one reusable desiccant that I purchased separately. Thank you very much.
