This is a rotating automatic pet feeder. I received it as a gift and tried it once, but it didn't suit my cat, so I'm selling it. It has been cleaned and its operation has been confirmed. There is no instruction manual, and the box has some stains, but the product itself has no noticeable stains. Please understand that it is not a new, unused item. A rotating automatic feeder that is useful when you are away from home or sleeping. Timer settings are available from 1 minute to 24 hours. ■ Dimensions: Approx.
