Attacked on the roof

I was cleaning the leaves out from a tight spot underneath the overhang of an upper roof when this little sucker came after me hissing and squeeking. lol

lol It's a very young squirrel.

When they roofed the flat sunroom, they closed off about a 2 foot wide area from the gutter to the wall of the house by installing apron flashing across the length.

However, they did not do anything to close off the ends. So critters were nesting behind there.

What is it and how did it get there?

Only problem is, this one's gonna be a little on the furry side, with fat cheeks and teeth like Buggs Bunny! :laugh:
