Sounds good:
PS. 1 .They have dogs.
The pussy squad may bolt at the sight of a lab and a beagle.
You need additional planing, liver threats for the dogs may help.
Of course if no dog present, you have no problems.
Also for maximum efficiency you may tie her to a post or similar, cats prefer to spray on vertical surfaces, Ginger Tom will have it easier.
Also the smell(just the smell) of bleach attracts some cats to spray, so once you get her, put a cloth smelling of bleach in her pocket.
PS.2.
I don't know what this is about (the plan) but its funny.
