People aren't the only ones who stay home when the weather gets brutally cold _ raccoons, squirrels and other wildlife are staying put as well. Brandon Kulosa is one of the founders of Animal Trackers Wildlife Company in suburban Chicago. He says critters that might otherwise be looking for a warmer space to call home or scurrying in search of food tend to stay put when the temperatures dip into the single digits or fall below zero. Why? Animals somehow know they'll burn more calories looking for food than they would if they just stayed put. When things heat up, Kulosa says to expect the critters to start checking to see if there's a way to get into warm buildings.
