I'm so very sorry that your trust was betrayed and for the loss of your beloved animals. Be sure to let others know that that woman should not be called for animal care. I hope your son is all right, and I know that it will be difficult for you to trust again. Keep in mind that your son may blame himself too and he may need some reassurance on this. Kids have a way of blaming themselves even when it isn't their fault.
I hope that in time you may be able to trust again, because we all have emergencies, and need support.
