A really close family friend of mine is an ASPCA employee. From the facts given in your post, nothing went "by the book". He is skeptical as to whether or not this lady even works for animal control. Like most others, I would suggest calling animal control...from there maybe call the police, and report this person. I have heard too many stories about stolen pets. Also tell your friend not to give out your personal info, your name and phone number would have been sufficient enough for them to follow up with you. Good Luck, and keep an extra eye out on your baby.
