This is the first time that I have had an automatic feeder.  I have two cats and one dog.  The product set up was so easy to do.  Just put the batteries in, set the time and the number of feeding and you're ready to go!  Would work well with either dog or cat.  Product is attractive and easy to clean.  For cats it would be an easy way to feed them if you are out of town for a few days and for the dogs that tend to overeat a great way to monitor the amount of food that they are eating. Feeding made easy!
