Understanding the “winter blues” in pets

Published: 29 January 2026

During the winter months, many of us feel a dip in our energy levels due to reduced sunlight disrupting mood-regulating hormones. This is often known as Seasonal Affective Disorder (SAD). But have you ever noticed your dog moping by the radiator, or your cat becoming a little more huffy than usual?

While pets might not experience SAD in the same way humans do, they are highly sensitive to changes in light, temperature, and our own moods. From dogs and cats to horses and exotic pets, the “winter blues” can affect the whole family.

 

Recognising the signs of SAD in pets

Because our pets can’t tell us they’re feeling a bit “meh” we have to look for subtle shifts in their normal routine and personality.

  • Dogs: You might notice a lack of interest in “zoomies” or toys. Some dogs become clingier, while others might bark more frequently due to boredom if walks are cut short by rain.
  • Cats: Many owners report their cats sleeping even more than usual or showing a bit of grumpiness and irritability.
  • Horses: With less time at grass and more time in the stable, horses can become frustrated. You might notice “stable vices” or a bit of cheekiness when handled as they burn off pent-up energy.
  • Reptiles & Birds: For exotics, the change is often physiological. Reptiles may become lethargic if their enclosure temperatures aren’t adjusted for the ambient drop in the room, while birds might pluck feathers or become unusually quiet.

 

 

Practical tips to help pets with SAD

1. Chase the light

Natural sunlight helps regulate melatonin and serotonin which are the hormones responsible for sleep and happiness. For indoor pets, move your cat’s bed or your rabbit’s run closer to a window or under a skylight. For dogs, try to schedule your main walk during the brightest part of the day, even if it’s just a quick 15-minute stroll around the block in the midday sun.

2. Prioritise indoor fun

When the weather is too beastly for long outdoor adventures, bring the stimulation inside. Hide high-value treats around the room for your pet to find or use lick-mats to keep their minds engaged while they’re indoors. If it’s too icy to ride, spend 10 minutes doing groundwork or grooming with your horse to maintain that vital bond.

3. Check their home setup

For exotic pets, winter is less about mood and more about environment. Ensure heat lamps and UVB bulbs are working at full strength. A small drop in temperature can slow down a reptile’s metabolism significantly, making them appear depressed when they are actually just too cold.

4. Hibernate exotics safely

For some species, this time of year isn’t just about slowing down, it’s about a total seasonal shutdown. If you own a tortoise, for example, the drop in light and temperature is a signal that it might be time for their long winter sleep. To ensure they stay healthy during this transition, take a look at our essential tortoise hibernation tips.

When blue becomes a red flag

It is important to remember that lethargy, changes in appetite, or withdrawal can also be signs of underlying physical illness. For example, cold weather can make joint stiffness or arthritis more painful for senior pets, causing them to move less.

As pet owners, we want the best care for our companions without the added stress of a big vet bill. This is where having a comprehensive pet insurance policy is invaluable.
