It is cold in India. Stray dogs literally shake while sleeping. I do not have enough blankets for them. What other things can Insulate cold air? Can paper do it? If not, what other things can be used? Thank You Humans.
I don't know if you are rural or in a city, but dried plants can help as well. A lot of heat will be lost because they lay on cold ground, so a pile of leaves, straw or hay may already help a lot.
Cardboard-boxes can be a help, too: they insulate from the ground, and shelter from cold winds.
Paper would insulate, yes, but it has the annoying tendency to be blown away, so boxes and dried plant-stuff may be your better option.
In general, the biggest problems for heat-loss will be a cold ground and cold winds, so anything insulating the ground and sheltering from winds should already help!
