Well not mine but this 120 year old building there is... or so they say! 

 

This scared me. Yes it really did... why did it scare me? well here is why baby birds. This is not just evidence that there is something in an attic ... it is evidence that the attic owners did not fully clean out their ... attic... When I buy an attic ... specifically off of ebay I make sure to taint it with my own urine and speak a slight chant. Clatu verata Ni... It's definately an N word.
