I wouldn't even question it!!! What can she do about it? What WOULD she do about it? Obviously she doesn't love it enough to spend any money or care on it ... so what is she going to do, hire an attorney to prove it is rightfully hers???? I think NOT!!! You don't have to let this woman into your home to look for the cat either .... just tell her you don't know where it is, and please leave you alone!!!!

This woman has me mad, as if you couldn't tell!

GOOD LUCK, and thanks for caring so much for this sweet girl!

edit: oh about the shots, etc. I would just keep her separated from your kitties until you can afford to have her re-tested (or tested for the first time) and up to date on her shots!
