A lot of humans suffer from Seasonal Affective Disorder (SAD).

But how about cats and other animals? Do they also suffer from this and how bad can it be?

In this article, you will find everything you need to know about this.

What is Seasonal Affective Disorder?

Seasonal affective disorder is a sort of psychological condition that causes mild depression. Researchers believe that this occurs because of the lack of sunlight in the winter. Without regular exposure to the sun’s UV rays, your brain doesn’t generate as much serotonin as usual. Serotonin is a “feel good” chemical we all naturally produce.

Despite what you might think, seasonal affective disorder doesn’t affect only humans. In fact, cats and many other animals can be influenced by the weather. This might be why you notice your feline friend acting differently depending on the time of year.

It is also possible that some people and animals get depressed in the winter because of vitamin D deficiency. Most of us get this vitamin from exposure to the sun, and it can affect a person’s overall mood. A lot of animal behaviorists believe that the same line of thinking can be applied to felines.

1. Lethargy

One of the most common signs of depression in both humans and other animals is lethargy. Is your cat lying around all the time, completely uninterested in anything? If so, it is possible that they are depressed due to the change in season.

It is also pretty common for cats to sleep a lot more than usual throughout the winter. This is because their bodies are producing more melatonin than usual. This particular chemical is responsible for inducing sleep, or at least playing a part in this.

2. Restlessness

Some cats that become depressed end up getting very restless. They won’t sleep as much as they usually do. You might notice your cat being even more active than usual, bouncing and jumping around all over the place. This sort of manic type behavior can indicate depression. While this may not be how we think of depression most of the time, it is something to consider.

3. Hair Loss

Severe depression and anxiety can cause some cat’s hair to fall out. While this is fairly uncommon, it is a possibility to keep in mind. If you notice your kitty’s hair falling out in tufts, it could be related to their mental health.
