Today an hour or two after feeding, we went out and found Ellie very ill. She was weak and in obvious pain. She appeared to have discharge and her temperature was very low. I took her to the vet immediately. He said she had the fast pneumonia and there was nothing he could do, she died a couple minutes later. He did give her a shot and it had no effect. He did give me a vaccine to vaccinate all the other animals that were around her. He told me that she was contagious, but if the others were vaccinated immediately, the chances were good that they would be fine. The cause was probably due to the drastic weather changes yesterday we were near 50 and dropped to -15 during the night. She appeared fine at feeding time. That is how it works, they are fine and suddenly within an hour or two they are gone. Apparently her temperature dropped, she began aborting and finally passed within a short period of time. When we found her, she could get to her feet and stood steady, within 15 minutes, we had to carry her and she could barely lift her head...20 minutes later she was gone.
