Finally, don't forget your pets. Even animals that live outdoors most of the year should be brought inside during times of inclement weather.
"If you're cold, your outdoor pets are cold," said Jonnie England, director of Animal Advocacy for the Metroplex Animal Coalition. "The body temperature of dogs and cats is just a little higher than a human's, so even though they're wearing 'fur coats,' they're still going to suffer in weather this cold. If it's not feasible to bring the pets inside the house, at the very least, they should be set up in a draft-free garage or storage building with plenty of dry, clean bedding."
