I hate to say it, but I to have a BEST freind that I would feel the same way about. Unfortunatly you are put in a hard spot, if it was me, I would also talk to her and let them know. Maybe you could ask them not to tell her, tell them to tell her it was adopted, Hope all works out for you. Freinds are freinds, animal people are animal people. My best freind is no good with animals, but Im trying to teach her. Just wish she would listen
