Shivering during heat cycle normal? For the past couple of days, my little 10 months old is showing signs of her first heat. She has not been fixed yet. She is acting a bit strange and is very clingy to me. Her vulva is swollen and she is liking it constantly. What is concerning to me is that she seems to be trembling or shivering and I'm not sure if it's normal or not. She also vomited some of her food this afternoon but other than that she's been eating, drinking and going the bathroom normally. |
