One of my cats was a small all black old female who never came on the sofa arm but when
I put ACDC Live in Donnington. She would suddenly appear besides me and watch the screen.
No other music or program had that effect on her.
As it's been suggested already, I would look for a common
exhaust conduit exit. Otherwise, I can't figure out where the smoke
would come from if there is concrete between the two houses.
Even if you decided to move, solving the smoke scent problem would
definitely help selling the house...
