Cat Shivers When Sleeping – Is Shivering While Sleeping Normal for Cats?
As a cat owner, you may have noticed your furry friend exhibiting various movements and behaviors while sleeping. These can include twitching, muscle spasms, and shivering. But is shivering a normal behavior in cats during sleep? Let’s find out.
First of all, it is essential to know that cats, like humans, go through different stages of sleep. Cats typically have short periods of deep sleep, known as REM (Rapid Eye Movement) sleep, and longer periods of light sleep. During REM sleep, their eyes move rapidly beneath their eyelids, indicating that they are dreaming.
Twitching, shivering, and muscle spasms are often associated with REM sleep and dreaming. These actions are believed to be the result of the brain sending signals to the muscles and nerves. Therefore, it’s quite common to see your cat shivering or twitching while in a deep sleep or catnap.
However, if your cat is consistently exhibiting more intense shivers, tremors, convulsions, or seizures, it could be a sign of a more severe health condition. In these cases, it is essential to seek veterinary attention to diagnose and address any underlying issues.
But for the most part, shivering while sleeping in cats is normal and nothing to worry about. It’s just a sign that your furry friend is having sweet dreams!

Note: Keep in mind that the type and duration of your cat’s sleep may vary depending on their age, health, and personality. Some cats are light sleepers and may wake up easily, while others may sleep for longer periods without interruption.
Potential Causes of Shivering When Sleeping
Shivering during sleep can be caused by a variety of factors. One possible cause is hypothermia, which occurs when the body temperature drops too low. If your cat is sleeping in a cold environment without adequate insulation from their fur, they may shiver in an attempt to increase their body heat. Providing a warm cat bed, blankets, or even a heating pad can help alleviate this issue.
However, shivering can also be an indication of underlying illnesses. Viral diseases, bacterial infections, and parasites can cause fever, which may in turn cause your cat to shiver during sleep. Issues with internal organs such as kidney problems, heart diseases, and respiratory problems can also lead to shivering. Additionally, neurological disorders may cause muscle spasms or tremors during sleep.
If your cat’s shivering is persistent or is accompanied by other concerning symptoms such as coughing, vomiting, or loss of appetite, it’s important to seek veterinary care. Your vet can help diagnose and address any underlying health issues.
| Causes of Shivering When Sleeping | Symptoms |
|---|---|
| Hypothermia | Feeling cold to the touch, seeking warmth |
| Viral Diseases | Fever, lethargy, loss of appetite |
| Bacterial Infections | Fever, coughing, vomiting |
| Parasites | Weight loss, diarrhea, lack of energy |
| Internal Organ Issues | Difficulty breathing, pale gums, decreased appetite |
| Neurological Disorders | Muscle spasms, tremors, seizures |
It’s important to monitor your cat’s behavior and look out for any symptoms of illness. Regular veterinary check-ups, vaccinations, and appropriate medications can help diagnose and address any underlying health issues.

Stress, Anxiety, and Behavioral Factors
If your cat shivers while sleeping, it could be related to stress, anxiety, fears, trauma, or other behavioral issues. When cats experience emotional distress, they may exhibit trembling or shivering as a response. Certain situations, such as loud noises or unfamiliar environments, can trigger a stress response in cats and cause them to shiver during sleep. It’s important to create a comfortable and safe environment for your cat to alleviate anxiety and promote relaxation.
Ensure that your cat has a cozy and secure space to sleep, such as a cat bed or a designated area in your home where they feel safe. Providing warm blankets and heating pads during colder months can also help keep your cat comfortable. Additionally, feeding your cat a balanced diet and ensuring proper hydration can promote a healthy sleep routine and reduce stress levels.
If you suspect that your cat’s shivering during sleep is related to stress or anxiety, speak with your veterinarian about potential solutions. They may recommend a behavior modification program, anti-anxiety medications, or other forms of treatment to help manage your cat’s emotional wellbeing.
