Automatic feeder??

Anyone have any recommendations for a good automatic feeder??

Ideally I'd like to find something that will keep wet food good for a while (maybe with some sort of icepack).

I have 2 boys and will be starting a job soon where I work 28 hour shifts. I have no problem leaving them lots of dry food out, but I'd like to find a solution for the wet...

Any thoughts??

thanks!
