Rocky's: Aww and I was hoping you were talking smack about someone from TCS. Ahh well.

Offer to go with her, when she wants to go adopt a new cat, and privately inform that shelter of what she did in the past and that she plans to make this new cat an outdoor cat.

Not only will hopefully the person at the shelter educate this lady, but also flat out might not adopt out to her. And might put her name on the "list" for other near by shelters and rescues to NOT adopt out to this lady.
