About Seasonal Affective Disorder in Cats

Seasonal affective disorder, more commonly known as the wintertime blues, is a mood disorder that causes depression during the colder, drearier months of the year. It is well-studied in humans, but many cat lovers also report seeing changes in the mood and behavior of their feline friends during the winter.

  1. Light Exposure

    • Cats, perhaps more so than people, are sensitive to changes in light. Less light in the winter may cause a decrease in natural brain chemicals, like serotonin, that increase mood.

      Open your curtains on sunny winter days and you may find your cat soaking up some rays. As long as your cat can't knock it over, leave a lamp on during dark days, preferably one with a full spectrum light bulb.

    Temperature

    • Temperature changes in the winter may disturb your cat's usual routine. Your cat may sleep near a heater or in front of the refrigerator or oven. Cold floors, especially in basements, may keep your cat from using the litter box. Move the litter box to a warmer place to prevent messes on your carpet.

    Sleep

    • One of the most notable symptoms of seasonal affective disorder is wanting to sleep all the time. Cats normally are good sleepers, but it's okay to wake your cat up for playtime. If your cat's lethargy ever becomes a serious concern, consult your vet.

    Exercise

    • People often are less active during the winter so we may not be the best playmate to our feline friends. Cats may need encouragement to get off the couch and be active. Try a new toy or put a bird feeder near a window. Cardboard boxes and paper bags may be all the exercise equipment your cat needs. Healthy adult cats have their own winter coat and may not mind a romp in the snow.

    Eating Habits

    • Like people, cats may overeat during the winter months. This can lead to unhealthy weight gain. Make sure you feed the recommended amount of cat food and remind holiday guests to go easy on the treats.

    Tips

    • The noise of holiday parties or extra guests may be stressful for your cat. Furnaces also cause sudden noises that can disturb a cat, especially if your cat's litter box is near the furnace.

      Older cats may be more susceptible to seasonal affective disorder. They likely will be attracted to a warm, fuzzy blanket on the back of the sofa.
