I have a resourceful coon that visits my deer feeder each night and shimmys up the legs of the feeder and spins the plate to get more corn for him and his buddies. I've looked at a few cages on Amazon, Academy, etc. All the ones I see look like the squares of the cage are big enough that the little critter could still get him arms through it. It's a regular tripod feeder with a 55 gallon barrel. Any suggestions?
