Why Does My Cat Sleep With His Tongue Out? [Causes & Remedy]

Cats are famously known for their love of sleep, often spending 12 to 16 hours a day napping in their cozy spots. During this time, many cat owners have observed their feline companions displaying some unusual behaviors, such as sleeping with their tongue sticking out. While this may seem strange or even humorous, it’s a behavior that can have a variety of causes. For a cat lover, it can be worrying to see a beloved pet in such a vulnerable state. Understanding why a cat sleeps with its tongue out, how to tell if it’s harmless or a sign of something more serious, and how to care for your feline friend in such situations can help provide peace of mind. Let’s explore the reasons behind this behavior, when it’s normal, and when it could signal a need for medical attention.

Why Does My Cat Sleep With His Tongue Out?

When a cat sleeps with its tongue out, it is typically a sign that something is different from the usual deep, restful slumber. The primary reason behind this unusual sight often lies in the relaxation of the muscles in their face. When a cat falls into a deep sleep, especially during rapid eye movement (REM) sleep, their jaw and mouth muscles can relax so completely that the tongue slips out unintentionally. This can happen when they are lying on their side or curled up in a position that lets their tongue fall out naturally.

However, there can also be other factors at play, ranging from medical conditions to stress and fatigue. The tongue is an important part of a cat’s daily life, used for grooming, eating, and communicating, so when it’s exposed in this way during sleep, it’s crucial to consider the context of the behavior. Cats are creatures of habit, and any deviation from their typical patterns should be observed carefully to assess whether it’s something harmless or a cause for concern.

Common Reasons

There are several common reasons why your cat might sleep with its tongue out. Let’s break them down:

  1. Relaxation of Facial Muscles: The most common reason for a cat’s tongue to fall out during sleep is simply muscle relaxation. When cats enter a state of deep sleep, particularly REM sleep, their muscles are at their most relaxed, and this includes the muscles around their mouth. As a result, their tongue can slip out, especially if they are lying on their side or in an odd position that makes it easier for the tongue to fall out of the mouth.

  2. Dental Issues: Cats with dental pain or issues, such as gum disease, tooth decay, or oral infections, may keep their mouths partially open when resting to relieve discomfort. In some cases, they may leave their tongue out while they sleep to avoid applying pressure on sore areas of their mouth. If you notice your cat frequently drooling or showing signs of discomfort while eating or chewing, this could be an indication of dental problems.

  3. Nausea or Gastrointestinal Issues: Cats with gastrointestinal discomfort, such as nausea or upset stomach, may also sleep with their tongue sticking out. This can occur because the tongue is naturally protruding as part of their body’s effort to expel something from the stomach, or as a reflex to help calm the nausea. If this behavior occurs alongside vomiting, lack of appetite, or lethargy, it could suggest a more serious underlying issue.

  4. Respiratory Problems: If your cat is experiencing difficulty breathing due to respiratory infections, asthma, or even heart disease, they might breathe with their mouth open or leave their tongue exposed during sleep. Cats may attempt to regulate their breathing while in a relaxed state, which can sometimes result in the tongue sticking out. If this is accompanied by coughing, wheezing, or labored breathing, it could indicate a respiratory issue.

  5. Heatstroke or Overheating: On hot days, cats may pant to help regulate their body temperature, much like dogs do. While panting, their tongues often hang out of their mouths. If your cat is overheated and is sleeping with its tongue out, it could be a sign that the cooling process is still occurring. It’s essential to ensure your cat has access to water and a cool environment during hot weather.

  6. Age and Cognitive Decline: Older cats may be more prone to sleeping with their tongues out due to age-related changes, such as weakened muscle tone or cognitive dysfunction. Senior cats, like elderly humans, can develop habits that are out of the ordinary due to the natural aging process.

When To Be Concerned

While it’s generally a harmless and temporary occurrence, there are situations where a cat sleeping with its tongue out should raise concern. If your cat’s tongue remains exposed for extended periods while they’re awake or they appear lethargic, there may be an underlying issue. Here are some signs to watch for:

  1. Persistent Tongue Protrusion: If your cat’s tongue is constantly hanging out, even when they are not sleeping, it may be a sign of a more serious medical issue. This could point to dental disease, neurological problems, or respiratory distress.

  2. Difficulty Breathing: If your cat is sleeping with its tongue out and seems to be struggling to breathe, this could be a sign of a respiratory infection, asthma, or even heart disease. Labored breathing accompanied by the tongue sticking out warrants a trip to the vet.

  3. Excessive Drooling: If your cat is drooling excessively, especially when sleeping with its tongue out, it could indicate dental issues, oral infections, or nausea. Drooling combined with the tongue hanging out may signal that the cat is trying to relieve oral discomfort.

  4. Changes in Behavior: If your cat seems more lethargic than usual, is losing weight, or refuses food, these signs combined with sleeping with the tongue out should prompt a visit to the vet. Gastrointestinal issues, such as nausea, can cause this behavior, as well as stress or pain.

  5. Signs of Heatstroke: If your cat’s tongue is out and they are panting excessively, particularly on a hot day, it could be a sign of heatstroke. Cats are prone to overheating, and this is a medical emergency that requires immediate intervention.

How To Respond As A Cat Owner

As a cat owner, it’s important to be attentive to your pet’s behaviors and physical cues. If you notice your cat sleeping with its tongue out, consider the following steps to respond:

  1. Monitor the Situation: Keep an eye on your cat’s behavior over the next few hours or days. If it’s a one-time occurrence, it’s likely nothing to worry about. However, if it continues or is accompanied by other symptoms, take note of any changes and consult your veterinarian.

  2. Check for Other Signs of Illness: Assess your cat for signs of discomfort or illness, such as loss of appetite, vomiting, coughing, or changes in their grooming habits. These could be indicators of an underlying issue that needs veterinary attention.

  3. Provide Comfort and a Calm Environment: If your cat is simply relaxing with its tongue out, ensure they have a calm and comfortable resting area. Make sure their environment is free of stressors and that they have easy access to fresh water, especially in warm weather.

  4. Keep Their Mouth Clean: If you suspect dental issues, maintaining your cat’s oral hygiene is essential. Regular teeth brushing and dental check-ups can prevent many common dental problems that could lead to discomfort.

When To Consult A Veterinarian

If the behavior persists or if you notice any additional concerning symptoms, it’s time to consult your veterinarian. Your vet will be able to conduct a thorough examination, including checking for dental disease, respiratory issues, or gastrointestinal problems. They may recommend diagnostic tests such as blood work, x-rays, or oral exams to determine the cause of the behavior and provide appropriate treatment.

Conclusion

Cats are complex creatures with unique behaviors that can sometimes leave their owners wondering what’s going on. While seeing your cat sleep with its tongue out can be a surprising sight, it’s usually a harmless quirk of feline behavior. However, it’s important to be aware of the context in which this happens and to monitor for other signs of discomfort or illness. If your cat’s tongue protrudes constantly, or if you notice any other unusual symptoms, it’s always a good idea to consult with your veterinarian to rule out potential health concerns. By paying attention to their health and well-being, you can ensure that your cat continues to lead a happy and healthy life, whether they’re snoozing with their tongue out or not.
