I believe that stuff could permeate 3 ft concrete walls. It knows no bounds.does Bear still have a sense of smell? I would think their aroma would be powerful - kind of musky.
I had some that walked on the outside sill of my basement windows. I could see & smell them go by when I was on BYC posting.I'd bang on the window and they ignored me. Even had a skunk walking that plank but, thought better not bang on the window and scare it. Does skunk perfume permeate glass?
