Forget to feed your cat? no worries... here's a machine to feed them. Problem solved!
Presumably inspired by Doc Brown's automatic dog-feeding Rube Goldberg machine from Back To The Future, this is a worthwhile (and relatively short) video of the automatic cat-feeding Rube Goldberg machine constructed by Joseph of Joseph's Machines, which is capable of removing a can of cat food from the fridge (then closing the door), taking the top off, and then catapulting it into the wall above the cat's dish.
