Thank you both for your replies. The vet would not take her today, so on Monday she has an appointment.

Yes the garage is heated/cooled for her, I am just not sure yet. If she tests Negative, she will probably be able to come inside the house.The lady said she could not wait that long to get her, so she won't be taking her. (oh well- her loss seeing as Sugar is the sweetest lovebird ever!) Again thank you for the replies! Have a good day.
