Don't leave pets outdoors when the temperature drops. Dogs and cats are safer indoors, except when taken out for supervised exercise. Regardless of the season, shorthaired, very young, or old dogs and all cats should never be left outside without supervision. Short-coated dogs may feel more comfortable wearing a sweater during walks.
 
  Pets who spend a lot of time outdoors need more food in the winter because keeping warm depletes energy. Routinely check your pet's water dish to make certain the water is fresh and unfrozen. Use plastic food and water bowls rather than metal; when the temperature is low, your pet's tongue can stick and freeze to metal.
 
  Warm engines in parked cars attract cats and small wildlife, who may crawl up under the hood. To avoid injuring any hidden animals, bang on your car's hood to scare them away before starting your engine.
 
  The salt and other chemicals used to melt snow and ice can irritate the pads of your pet's feet and may be harmful if ingested. Wipe the feet with a damp towel before your pet licks them to remove snow packed between your pet's paws. Pet-friendly ice melts are available at many pet supply stores across the nation or online.
 
  Antifreeze is a deadly poison, but it has a sweet taste that can attract animals and children. Wipe up spills and store antifreeze (and all household chemicals) out of reach. Better yet, use antifreeze-coolant made with propylene glycol, which is less toxic in small amounts than traditional ethylene glycol antifreeze.
 
  No matter what the temperature, wind chill can threaten a pet's life. A dog or cat is happiest and healthiest when kept indoors. If your dog spends significant time outdoors, however, he/she must be protected by a dry, draft-free doghouse that is large enough to allow the dog to sit and lie down comfortably, but small enough to hold in his/her body heat. The floor should be raised a few inches off the ground and covered with cedar shavings or straw. The house should be turned to face away from the wind, and the doorway should be covered with waterproof burlap or heavy plastic.
 
  If you're feeding homeless cats, be sure to provide an insulated shelter for them. Information about building a shelter, spaying and neutering and more is available at humanesociety.org/feralcats.

IHOP still only uses eggs from hens confined in cages so small they can't even spread their wings. But thousands have urged the restaurant chain to start using eggs from cage-free hens.
