Automatic Pet-Cat Feeding Machine

My cat reminds me when I forget to feed it by meowing. I don’t mind feeding it, but I also have better things to do so, the Automatic Pet Cat Feeding Machine.

The machine has a shallow cup. Above the cup are two electrically charged metal plates. The plates are charged with a small step-up transformer to 35K volts, not enough to spark by themselves, but enough to discharge through an object that may pass between them with sufficient current to ignite a burnable object. An upper cover protects the plates and cup from rain and to prevent false strikes. Solar panels with suitable controls maintain a storage battery fully charged to avoid the need for a long wire to the house. Finally, a light sensor below the plate is connected to a bell to ring whenever an object falls from the plate onto the ground.

The machine works like this: The machine hangs from a branch in a tree near the house. A few grains of bird-feed are placed into the cup. The cat is fed by any local bird attracted to the cup with the bird-feed. As it flies into the machine, the metal plates discharge through the bird causing their feathers to burn as the shocked bird falls below past the light sensor to ring the bell. The bell attracts the cat to come and find a perfectly cooked, defeathered bird for dinner.

Meanwhile you can go on with your life. Since the bird will never get to the bird-seeds, the machine will last a long time. I would recommend changing the bird seeds every few years to maintain their attractiveness.
