I purchased this pet feeder to feed our cat when we went away on weekend trips. Our cat, who is very food aggressive, is unable to get at the food for the future days, much to his dismay. This feeder is very easy to set up, and though I do not use it for canned food, it has ice packs that can keep canned food cool and fresh. I would recommend this feeder for anyone who takes short trips and has a cat that needs to be on a feeding schedule.
