Automatic pet food dish

I want to make a pet food dish that rations out pet food at specific intervals. Something similar to this http://www.petronic.com/sixday.htm it doesn't have to be a circle, I could probably figure out how to do it with a pulley system and motor if it was straight, but I need to find a timer to trigger the motor. Does anyone know where to get a timer like that, or what I should search for. I've never built anything before, so I don't know anything, or what to search for. Thanks for any help.

Did you see Back to the future. Doc brown had an automatic pet food dispenser for his dog Einstein.

you could get a timer (it looks like a wallwart) that's meant for christmas lights and just attach a motor (not direct unless it's a 120volt AC motor!)
