This product does not work for a dog. I put 2 meals in to try it out, and set the timer for 12 hours. The battery died in about an hour, and my dog got into both food trays. She was then overfed. I tried to not give this product ANY stars, but the screen won't let you get past if you don't rate at least one star. It does not deserve ANY stars. I have seen this product in many places...NOBODY should sell it !!!
