Well I have a 10 month old siamese cross queen that my much younger sister rescued from a tree. Anyway, she was in heat, and she'll wait by the door. One of our neighbors stopped over and she got out. We didn't see her for a while. But she was out of heat when she came back. Her nipples are redder and she wants more attention, and she is a bit rounder than she was. She also eats more and cuddles more. Is she pregnant? We didn't get her spayed because every vet within 50 miles is booked until May. I know it's entirely possible that she is pregnant, because our neighbor has one tom that they have not been able to catch, so he is not neutered. What should I do???
