Review on MCR Medical Silver Emergency Blanket by Jeffrey Sanders

I have two old cats who never get warm in winter. My idea was to use mylar to reflect the heat of the animal's body in the same way it would be used by a human. I bought some cheap fleece blankets from a big store nearby. I folded the mylar blanket so that it was the lining in the middle of the fleece blanket that was folded to fit the cut out cardboard. TA Dah! Fried cats.
