Bests & Worsts Reviews from Amazon

I have to admit, I didn't buy these for me. My husband and I have been taking care of our neighbor's abandoned cat for close to a year now. We used to keep him in our apartment (despite a no-pets clause in our lease) but when he got fleas, we decided it was time to stop bringing him in. It's getting cold now, so I built him a shelter out of a plastic storage bin, insulating foam cut to fit around each side of the bin (including top and bottom), some straw and one of our blankets that he loves. I was worried that plain insulating foam might not keep out the cold Philadelphia winter, so I ordered these blankets and wrapped one around each piece of the foam so that the entire bin was insulated. A few weeks ago we had a cold snap and the cat was hanging out in the shelter. While he was in there, I stuck my arm in to get his food bowl to refill it and even though it was barely 30 degrees outside, I swear it was at least 70 degrees in the shelter - the Mylar blankets retained so much of the little guy's body heat that it was downright comfortable, even with the opening we cut into the box to let him come and go. I'm not worried about him freezing to death anymore. If they work for that, I'm sure they're great in an emergency.
