The feeder has a generous capacity of 3L/12.7 cups, allowing it to hold a significant amount of food.  The actual number of days' worth of food it can hold will depend on your specific feeding settings.  For example, one user shared their experience of setting the feeder to dispense 3 portions four times a day during a 5-day vacation, and they still had plenty of food left.  The feeder's large capacity and customizable portion sizes make it suitable for accommodating your cat's needs over several days without frequent refilling.
