well, its unfortunate that poor cat was euthanized ... but you didn't do it. Someone who mistakenly didn't think the cat was worth anything euthanized it. If she "sues", she wont win. Especially if you have pics or some kind of evidence that the animals were not cared for while with this woman.

How far away does she live from you? When my mom and I had problems from her psycho ex, we went to night court and got a order of protection I think its called. He goes to jail for 60 days everytime he comes near our "area". Maybe you should do the same.
