A broken automatic door from Amazon killed my friend's chickens. Not quite an automated feeder, but since the door opening was a condition of the chicken eating, similar situation. There are some interesting points this brings up expanding beyond the whole internet-of-things/robot-ification of the world. a) Google, Amazon, and Facebook mean really bad products can get global reach instantly. Even Walmart had pretty big hurdles which products had to cover. There are some controls in place, but the problem has to be pretty large to register. b) Products accidentally killing humans let alone animals is a very common occurrence, see global vehicle deaths. Plenty of stories of very dangerous products litter Amazon reviews. c) The companies making a lot of money from bad products are the online marketplaces. Somehow this hasn't hurt their brands too much yet, which is interesting. d) There is a market need for a better rating and review process for everything. Given the more reviews are viewed publicly the greater their perverse effects are so maybe it won't even be publicly viewable. I spend a lot of time thinking about the d) problem. The scarier thing is that this already exists to a large extent in many businesses using machine learning methods and labeled fraud detection. What happens in a future IOT where you product doesn't function on purpose?
