I keep bird seed in an old tub of protein mix. It's usually in my shed, but I had filled the feeder up this morning and put the tub on my front porch.
Came back from a trip to the store this afternoon and saw two squirrels fleeing my front porch. They looked guilty.
Here's what they did.
The lid had been securely fastened
Somehow they managed to get it unscrewed and were happily helping themselves to the seed inside.
Who needs opposable thumbs when you have razor sharp incisors and a rodent's cunning?! I better watch my back.
