It is Squirrel Week! How well do you know squirrels? (I, apparently, do not know squirrels well, even though I thought I had learned a lot during March Mammal Madness. Back to the books!)

In probably unrelated news, an angry badger has shut down part of a Scottish castle. Best line: “There was no indication as to why it was angry.” (Perhaps it’s upset there is no Badger Week?)

UPDATE: There is indeed a Badger Week, and it's Scottish Badger Week, at that! Calm down, angry badger, you'll have your time in the spotlight next month.
