From the Humane Society of the United States:
- If pets cannot come indoors, make sure they are protected by a dry, draft-free enclosure large enough to allow them to sit and lie down, but small enough to hold in the pet’s body heat. Raise the floor a few inches off the ground and cover it with cedar shavings or straw. Turn the enclosure away from the wind and cover the doorway with waterproof burlap or heavy plastic.
- Salt and other chemicals used to melt snow and ice can irritate a pet’s paws. Wipe their paws with a damp towel before your pet licks them and irritates their mouth.
- Antifreeze is a deadly poison. Wipe up spills and store antifreeze out of reach.
From the American Red Cross:
- If possible, bring your pets inside during cold winter weather. Move other animals or livestock to sheltered areas and make sure they have access to non-frozen drinking water.
- If the animals are outside, make sure their access to food and water is not blocked by snow drifts, ice or other obstacles.
