The APOP (Association of Pet Obesity) reported that dogs and cats gain an average of almost 1/2 pound during the months of October and February (which is equivalent to about 2-4 pounds for people). This could be the result of several obvious reasons like the weather causing your pet to be inside more often, which could result in less activity, and overfeeding, especially during the holidays. But one less obvious reason could be because, like many people, the cooler wintery days can lead to seasonal depression. That’s right. Your furry little baby could be feeling depressed. But don’t worry, there are things you can do to help. Since lack of much sunshine has been known to play into seasonal depression, it’s important to make an effort to boost the light exposure for Fluffy. Place his bed near a window or a skylight. Be sure to leave the blinds open and turn on indoor lamps around his favorite resting spot. As his mood starts to boost, keep him mentally engaged by playing games or teaching him a trick more often. These small changes can make a big difference in his mental well being and keep him from gaining those extra pounds. According to the American Veterinary Medical Association, 58% of U.S. cats and 53% of U.S. dogs are considered overweight or obese.
