Raccoons?

Imagine my surprise to find the last blueberries gone! I had placed sturdy metal stakes into the ground. On top of the stakes I have plastic two liter bottles with the bottoms cut out to make climbing (or landing) impossible. I have covered everything, even the top, in netting. Well, something clever pushed the stakes so they tilted in the soft rain-soaked soil. This same something clever pushed the loose netting close to the blueberries, close enough to eat them. I've been outwitted by a wascal.
