I was skeptical at first if my kitten would even use this feeder given its size due to fact that she eats out of a little dish but she ate out of it within an hour of setting the timer. It was easy to set up and program. It dumped the food right on time completely. No residual food left in the tray. We slightly moisten her food to add probiotic. It's not a problem if the food is not too damp. I guess my only question would be battery life. It takes 4 D's and if that had to be changed often that could be costly. So far it's been good. Perhaps having a power cord with battery back up would be a good upgrade if they want to improve on this product.
