Keep your cat inside. Outdoors, felines can freeze, become lost or be stolen, injured or killed. Cats who are allowed to stray are exposed to infectious diseases, including rabies, from other cats, dogs and wildlife.

During the winter, outdoor cats sometimes sleep under the hoods of cars. When the motor is started, the cat can be injured or killed by the fan belt. If there are outdoor cats in your area, bang loudly on the car hood before starting the engine to give the cat a chance to escape.

Never let your dog off the leash on snow or ice, especially during a snowstorm—dogs can lose their scent and easily become lost. More dogs are lost during the winter than during any other season, so make sure yours always wears ID tags.

Thoroughly wipe off your dog's legs and stomach when he comes in out of the sleet, snow or ice. He can ingest salt, antifreeze or other potentially dangerous chemicals while licking his paws, and his paw pads may also bleed from snow or encrusted ice.

Never leave your dog or cat alone in a car during cold weather. A car can act as a refrigerator in the winter, holding in the cold and causing the animal to freeze to death.

Like coolant, antifreeze is a lethal poison for dogs and cats. Be sure to thoroughly clean up any spills from your vehicle, and consider using products that contain propylene glycol rather than ethylene glycol. Visit the APSCA Animal Poison Control Center for more information.

Make sure your companion animal has a warm place to sleep, off the floor and away from all drafts. A cozy dog or cat bed with a warm blanket or pillow is perfect.
