When I first moved to the country I lived in a very old victorian home circa 1892. The attic had it's very own separate entrance and stairwell leading up to it. My first summer there, we had some work being done on the HVAC and apparently someone left the door open. I lived for 2 weeks with a skunk in the attic before we finally trapped him. Let me tell you, the smell will knock your socks off. To make matters worse, I was in the first trimester of my pregnancy.
