I don't really see how it could kill the cat. I guess maybe if it fell off the wall and landed on one but since it's mostly light plastic and tape, I doubt it would hurt the cat much if he/she failed to dodge the falling device. If you're worried about starvation, the article mentioned that this was only for the morning meal, so that the cats won't drag their human out of bed. If it malfunctions and doesn't turn on, I suspect the cats would fall back to dragging their human out of bed. This isn't for long term "away" feeding - the human will know it malfunctioned long before the cats are in any danger of starvation.
