ASA Techmed Emergency Mylar Thermal Blanket + Foil Space Rescue Blanket, 55×84in NASA Heat Retention, Waterproof Outdoor Survival, Silver – 20 Pack

I use them for feral cats and they seem to help keep them warm. At first they didn't like the crunchy sound they made so I put them under the straw or in between blankets. I'm putting one in my car for emergencies. Generously sized and reasonably priced. I cut them in halves or quarters to fit the shelter.

these heat blankets are so good I use them as a lining for my pets enclosure to keep the warmth in soy pets don't get cold also put an extremely tight layer of plastic over the blankets for extra protection and insulation I give them two thumbs up approval

I like to have these in case of emergencies. I have distributed them to my family, just in case of road break downs.

Bought for everyone to have for their vehicle's. opened one and tried it out juat to see if it would keep you warm. it did its job. good purchase.

Am using to line a feral cat shelter. So this package has the right amount needed. A great value for the amount. This buy will keep my kittys warm for a Montana winter.

Great to have in an emergency. Keep in the car and in the house.

Bought these for my family %26 myself

My grand daughters love it

They seem really thin and tear easily but I used one to keep cold out of a drafty window and it seems to help.

it was warm. had to change it daily because it tears easy. my cat loves laying underneath since it's so warm to her.
