How can we get updates on possible cougar sightings? We live near the river and had something large on our roof Halloween night

When a cougar is reported in a neighborhood we will usually investigate if there is enough information and it is timely enough.  Usually, cougars do not pose a threat when they are just passing through.  However, if they are repeatedly seen in a residential area or have killed pets or livestock, then we become involved.  However, something large on a roof could be anything including house cats, raccoons, or even a Halloween reveler throwing something.  If you see tracks or sign or actually see a cougar, please let us know.  Thank you.
