Query: Waste of Money

We followed the directions with gradually progessing our cat with using the automatic feeder. We then setup the feeder, it worked correctly for a short time, less than a day. Then it did not keep with the scheduled times setup for feeding our cat. It would go off at odd times of the day/night and being off by 3-4 hours of the scheduled times. In a day or two the mechanics of pushing the food through stopped working; however, the digital reader would show that number of meals given based on specified times scheduled. Then everything mechanical stopped working all together. This ended in up being a large waste of money.....
