When Morris tweets a message to @FeedToby, the machine sets off a buzzer to get the terrier's attention, and then a printer motor pulls open a trap door that releases dog food into Toby's bowl. It even has a webcam, so Morris can watch Toby enjoying his snacks.
"At first, he didn't know what was going on. Now he sits underneath, wagging his tail and waiting for the treats to drop," Morris said.
Thus far, the system has only run into one snag: Morris' friends and family liked the Twitter setup so much that they sent Toby too many treats, so the food machine now only works from 9 am to 9 pm.
