The picture says it all!
My cats enjoy the auto pet feeder. The feeder works on a timer, allowing you to set up to 8 feedings by configuring the start time and end time of the feeding. The feeding time will vary depending factors such as the size of the food. I have found that small food pieces fall out faster than large pieces. My feedings are approximately 30 seconds each, and I have configured about 4 feedings per day (for 3 cats). They also get some treats when they are good kitties (which is always!).
The problem that occurred (as seen in the picture) was caused because I started the feeding at 11:00pm, and then configured the feeding to stop 30 seconds later. Unfortunately (for me), I set the end time for AM, which means the feeder was configured to continue dropping food throughout the night. The cats loved it (because they didn’t have to clean it).
This feeder is great because it allows you to store many weeks of food (our cats use the medium size feeder). We do not leave our cats alone for extended periods, but its still nice to have a low maintenance feeder. If we leave our cats alone for a day or two, we can trust that the feeder will feed our cats, unless the power goes out, of course.
I also previously owned the auto pet waterer. The cats enjoyed the filtered running water, but the product I received was not built to last. There is also alot of maintenance required, which involved cleaning the unit every 3 weeks or so. The motor was a little too noisy for my liking, and would sometimes stop dispensing the water. I fought with the unit for many months, until one day the water starting overflowing out of the unit. At this point, I no longer trusted the unit and I disposed of it. Conceptually it is a great product, but it did not work out for us.
