I’m confident that we have a unwanted guest, but I’m not sure what/who. It’s usually active in the dawn or early morning. I can hear it scrapping stuff up there but it makes no vocal sounds, and it doesn’t sound small (but not totally sure though). It didn’t come through the access to the attic, because that panel is in the house.

So, I’m not sure what to do next. Should I let it be? Call a professional? Try to take care of it myself? Ask someone I don't like to handle it?
