I have not checked but came home from work and put on my thin cotton plaid pajama bottoms and short sleeved tshirt. Wrong! Not long before I was in thick sweatpants, long sleeved thermal shirt and heavy duty socks. And I am still cold ... down deep in my bones type of cold. I'm looking at a great big warm buddy named Kevie on the bed now. He loves to snuggle and there is my warmth when I fall asleep tonight.
What a sweet boy!
