PLEASE bring your family animals inside! An enclosed porch, a mud room, a laundry room, a basement, all of these are better than a scared, lonely animal freezing on a chain or a flimsy dog house. The coats of domestic animals are NOT made to protect them against a snow storm.
If you know of a stray animal in your neighborhood, consider creating some shelter around a porch for them. There are easy DIY cat or dog house plans on our Tumblr feed, through ASPCA’s site or on Google search. When padding out an outside emergency shelter please use straw and not a blanket or towel that can get wet and hold the cold.
