The American Society for the Prevention of Cruelty to Animals, says, "If it's too cold for you, it's probably too cold for your pet."

Tips to keep animals safe:• Keep cats indoors because many seek warmth by crawling into car engines, which can be dangerous or fatal.• Dogs also should be kept inside if possible, but if they are outdoors, they should have a draft-free shelter large enough to stand and turn around in, yet small enough to retain body heat. Use a layer of straw or other bedding material to help insulate your pet against the cold. Blankets will work but they do freeze, so check them often. Change bedding on a regular basis because if it gets wet from snow, rain or urine, it can freeze quickly.• When coming indoors from outside, wipe their paws once inside. Tender pads will get cold just like human hands and feet and can get frostbite.• Outdoor animals typically need more calories in the winter to produce body heat. Increase the amount you feed your pet if outside. Also, remember food and water will freeze quickly in subzero temperatures. Indoor-only animals may actually need fewer calories to avoid weight gain from lack of outdoor exercise.• Pet owners should walk outdoor animals to help them stay warm because their body temperature can drop quickly and cause hypothermia. Breathing bitter cold air can also cause a buildup of moisture in the animal's lungs and cause respiratory problems or pneumonia. These problems can occur quickly in cold temperatures, but it can happen quicker, depending on the animal's health, age and the type of animal.Sources: American Humane Association and ASPCA
