Aly, I don't think you have anything to worry about! Let her demand to meet with anyone and everyone at the shelter, there is no way she can take him from you.

So what she has vet records from March. Has she checked the calendar? It's July! Nookie has been in your care for weeks now. Didn't you say he was found in May or June?

Are you fostering Nookie or have you adopted him? Perhaps you had mentioned it before and I missed it. If you have adopted him, he is yours! And if you are fostering, he belongs to the shelter who can refuse to give the animal back to the old owner.

Keep us posted!
