The mini learns to open a jar

I’ve seen videos of squirrels running obstacle courses and other crazy stuff, so I figured I would start training my squirrels to do some things.
I am not really training them, so much as letting them use their little brains to figure stuff out.
I started with a miniature dresser with drawers. I put peanuts in the drawers and they quickly learned how to open them. They are a bit rough on the wood though. At least it keeps the Blue Jays from stealing the nuts!
So here is the jar with a few peanuts in it. I first used a smaller jar, but they wanted to just cary the whole thing up a tree.
