Ha! Those 'coons look awfully fat for this time of year!
If you could electrify just the feeder's housing, it would stop the stealing.
A cheap HF solar fence charger should do the trick. I think you could set your feeder on a sheet of aluminum or steel, then on a smaller sheet of rubber or plastic to insulate them. Place the fence charger on top of the feeder. Run the hot wire to the metal sheet, the ground wire to the metal feeder housing. When a coon steps on the sheet metal base, if he then touches the feeder housing, he get zapped.
OK, it may not work, but it's a lot fun to think about.
