GREAT news!

Instead of a fish net - use a blanket or large towel. She could get really tangled in the netting!

Maybe just you and one other person she knows well should go (with the towel/blanket) and just talk softly to her, coaxing her out. Rattle a bag of treats, too.

Or - borrow a live trap and put really stinky sardines in a dish, and put it near the edge of the deck. One of the shelters may have one you can borrow.

Also - maybe edit your title to say "Update # __, advice please" (whatever post # it is). There are lots of people here with good ideas to catch her.

Good luck!
