Sadly, the Harder M tries to "catch" her, the more fearful she may become.

It may be best if YOU, and only you, try to approach her -
she may be very much afraid of "men" in general due to her
previous "owner".

Get some very small (bite-sized) treats, and try "tossing" them in
her direction - LOTS of treats BEFORE you try to touch her.
And if she'll follow you to get treats, try getting her to
follow you into a garage or enclosed porch - so you can close
a door and confine her.

And when you do manage to "capture" her - don't rush to touch her
for a while - just sit down and keep "tossin treats" - let
her come to you.

After you capture her - be sure Mr. M repeats the "treat tossin"
BEFORE he tries to touch her.

Good Luck!
