Will take pic after I built it up tonight.
24” x 24” chicken wire mesh and only 6” diameter cardboard in the center with 5” pan on top, then it doesn’t have any cardboard to stand on the hind legs. It can’t stands on the pan to eat food unless it jumps over the chicken wire and landed on the pan (if it does this then it’s not a real raccoon but a Bot with the latest AI software running). It either touches the food pan with highly sensitive/dexterity paws, or licks the pan and receives a conditional response shock. This won’t kill cats as I had seen it in action when I used this method to deter the cats from harassing my outdoor canaries (the gangs of cats first got on and sat on the grounded chicken wire mesh (placed a few inches away from the bird house perimeter), licking their lips and sharpening their claws with a file, until one of them reached up with front paws to climb up the chicken wire bird house, then I heard a high pitch Meeeeoooo, and its arcing back was like a deep U shape, spring off 4 ft high like a rocket, and all ran away for a few weeks, then the next gang came again).
Yes, I have to be very careful with this simple 110v setup, but this is a quick solution for tonight. I will use one of the cheap Polaroid camera flash light circuit – high voltage discharge flash light with over hundreds of volts but low current so it is not deadly to human and animal but a good painful shock – instead of 110v household power.
