Sleep apnea is a serious condition that affects the quality of sleep and overall health, but did you know it’s not just a human problem?

Cats can suffer from sleep apnea too. While it may seem unusual, feline sleep apnea can lead to disrupted sleep, breathing issues, and long-term health risks for your pet. If your cat snores, gasps for air, or seems overly tired during the day, it could be more than just a harmless quirk. In this article, we'll explore whether cats can have sleep apnea, the symptoms to watch for, and how to ensure your feline friend gets the restful sleep they need.


What is Sleep Apnea?

Sleep apnea is a condition in which breathing repeatedly stops and starts during sleep. While it's most commonly discussed in humans, sleep apnea can also affect animals, including cats. This disorder leads to frequent sleep interruptions, causing fatigue and other health problems in both humans and animals.

It’s important to note the difference between snoring and sleep apnea. While snoring is the sound caused by the vibration of soft tissues during relaxed breathing, sleep apnea involves actual pauses in breathing, which can be far more serious.

There are three main types of sleep apnea:

  • Obstructive Sleep Apnea (OSA): The most common type, caused by a physical blockage in the airway, often due to relaxed throat muscles or excess tissue.
  • Central Sleep Apnea (CSA): This occurs when the brain fails to send proper signals to control breathing.
  • Mixed Sleep Apnea: A combination of both obstructive and central sleep apnea, leading to more complex symptoms.

Understanding these types is essential when evaluating sleep apnea in cats, as the cause of their sleep issues can vary.


Can Cats Have Sleep Apnea?

Yes, cats can have sleep apnea. Though less commonly discussed compared to humans, feline sleep apnea is a real and serious condition. This sleep disorder in cats involves interruptions in breathing during sleep, which can disrupt their rest and impact their overall health.


What are the Symptoms of Sleep Apnea in Cats?

Sleep apnea in cats can be difficult to spot, as it often occurs during sleep. However, there are several key signs to watch for. If your cat shows any of the following symptoms, it might indicate an underlying issue with their breathing during rest. Below are the most common symptoms of sleep apnea in cats:

 Symptom Description
Loud Snoring Persistent and loud snoring during sleep, beyond normal snoring levels.
Gasping or Choking Sounds Gasping, choking, or wheezing noises as the cat struggles to breathe.
Pauses in Breathing Noticeable pauses or irregular breathing patterns while the cat is asleep.
Restlessness During Sleep Frequent movement or shifting positions, indicating breathing discomfort.
Daytime Fatigue or Lethargy Excessive tiredness, lack of energy, or reduced playfulness during the day.
Irritability or Changes in Behavior Unusual irritability or anxiety due to disrupted sleep.
Open-Mouth Breathing While Sleeping
The cat may breathe through its mouth instead of the nose during sleep.

 


What are the Causes of Sleep Apnea in Cats?

Sleep apnea in cats can be caused by several factors, most of which are related to the cat's respiratory system or overall health. Identifying the underlying cause is crucial for proper treatment and management. 

Obesity

Similarly to humans, the relationship between sleep apnea and weight goes hand-in-hand. Excess weight can lead to fat deposits around the upper airway, causing congestion during sleep and leading to sleep apnea.

Upper Respiratory Infections

If your cat has a cold or a respiratory infection, it can cause inflammation in their nose or throat, and block airflow, making it difficult for cats to breathe properly while sleeping. This is similar to how people might have trouble sleeping when congested.

Allergies

Just like humans, cats can suffer from environmental allergies to things like pollen, dust, or mold. These allergies can block their nasal passages, leading to breathing issues, especially at night.

Nasal or Throat Polyps

Growths or polyps in the nasal passages or throat can obstruct airflow, leading to breathing difficulties and sleep disorders.

Brachycephalic Breeds

Cats with flat faces, like Persians or Exotic Shorthairs, have shorter nasal passages, which can make it harder for them to breathe or restrict airflow. This is similar to how some flat-faced dog breeds and humans with smaller airways are more prone to sleep apnea.

Genetic Predisposition

Some cats may be genetically predisposed to developing respiratory problems, including sleep apnea, due to inherited conditions.

Airway Obstructions

If your cat has something blocking their airway—whether it's a foreign object or a structural issue in their nose or throat—it can cause sleep apnea. This is like when people have a deviated septum that restricts their breathing during sleep.


Which Cat Breeds Are More Prone to Sleep Apnea?

Certain cat breeds are more likely to develop sleep apnea, especially those with unique physical traits that affect their breathing. These breeds, particularly brachycephalic (flat-faced) cats, are more prone to airway obstruction due to their facial structure. Here are the breeds most at risk:

  • Persian
  • Exotic Shorthair
  • Himalayan
  • British Shorthair
  • Scottish Fold

Brachycephalic (flat-faced) breeds tend to have shorter airways and narrower nasal passages, which can restrict breathing. This puts additional strain on their respiratory systems, especially when they are relaxed during sleep. As a result, these cats may snore loudly or experience pauses in breathing—both common signs of sleep apnea.


How Does Sleep Apnea Affect Cats?

Sleep apnea can have a range of negative effects on a cat’s health, both short-term and long-term. Here’s how it can impact your feline friend:

Short-term effects

1. Interrupted Sleep

Just like in humans, sleep apnea causes repeated interruptions in breathing during sleep. This leads to poor sleep quality, leaving the cat feeling tired and lethargic during the day.

2. Daytime Fatigue

Constant interruptions in sleep prevent your cat from getting restorative rest, leading to persistent fatigue, lethargy, and reduced energy levels.

3. Irritability and Behavioral Changes

Lack of proper rest can make a cat irritable or more anxious than usual. They may become less playful or more withdrawn.

Long-term health impacts 

1. Weight Gain or Overweight

Poor sleep can affect a cat’s metabolism, potentially leading to weight gain. This can create a vicious cycle, as obesity is both a cause and consequence of sleep apnea.

2. Cardiovascular Problems

Sleep apnea can strain the heart over time, potentially leading to heart disease, high blood pressure, and an increased risk of heart failure.

3. Respiratory Issues

Untreated sleep apnea may worsen existing asthma or respiratory conditions or lead to chronic breathing difficulties, making it harder for your cat to breathe comfortably even when awake.

4. Decreased Quality of Life

The combination of fatigue, irritability, and potential long-term health problems can significantly shorten your cat’s overall quality of life.


How to Diagnose Sleep Apnea in Your Pet?

Diagnosing sleep apnea in cats can be challenging, but veterinarians use a combination of clinical observation, diagnostic tools, and the owner's reports of symptoms to assess the condition. Here’s an overview of the diagnostic process:

Clinical Examination

The vet will start with a physical exam, paying close attention to the cat’s respiratory system. They’ll check for any signs of airway obstruction, nasal blockages, or other respiratory issues that may be contributing to sleep apnea.

Owner’s Observations

Your observations of your cat’s sleep behavior are critical. Noting symptoms such as loud snoring, gasping for air, or frequent waking during sleep can help the vet narrow down the diagnosis.

Medical History Review

The vet will ask about your cat’s medical history, including any existing conditions like obesity, respiratory infections, or allergies, as these can contribute to sleep apnea.

Imaging Tests

X-rays or CT scans may be used to examine the cat’s airways, throat, and nasal passages for structural abnormalities, such as polyps or tumors, which could be obstructing airflow during sleep.

Blood Tests

Blood tests may be conducted to rule out other underlying health conditions, such as thyroid problems, infections, diabetes, or anemia, that could be contributing to sleep disturbances.

Sleep Study (Polysomnography)

In some cases, a specialized sleep study may be performed at a veterinary clinic. This involves monitoring the cat’s breathing, oxygen levels, and sleep patterns to detect interruptions caused by sleep apnea.

Pulse Oximetry

Pulse oximetry is a non-invasive test that measures oxygen saturation levels in the blood. A drop in oxygen levels during sleep can indicate sleep apnea, providing additional data for diagnosis.

Once diagnosed, the vet will prescribe appropriate treatment options, which may include lifestyle changes, medical interventions, or even surgery, depending on the cause and severity of the condition.


What are the Treatment Options for Cat Sleep Apnea?

Treating sleep apnea in cats often requires a combination of veterinary or expert care and home management strategies. Depending on the underlying cause of the condition, several treatment options can help alleviate symptoms:

Regular visits to assess treatment effectiveness and make adjustments.​

Managing Cat Sleep Apnea or Cat Snoring at Home

While veterinary care is essential for diagnosing and treating sleep apnea in cats, there are steps you can take at home to help manage the condition:

Weight Management

If your cat is overweight, focus on a healthy diet and regular exercise. Weight loss can reduce fat around the airway, improving breathing during sleep.

Maintain a Clean Environment

Keep your home free from dust, allergens, and irritants that could worsen breathing issues. Regularly clean your cat’s bedding and living spaces to minimize allergens like dust or dander.

Monitor Breathing Patterns

Regularly observe your cat’s breathing during sleep. If the episodes of snoring or apnea become more frequent, track them and consult your vet for further guidance.

Reduce Stress

Stress can exacerbate breathing problems. Ensure your cat has a calm and relaxed environment to help alleviate any anxiety that might worsen the condition.

Humidifiers

Using a humidifier in your cat’s sleeping area can help keep their nasal passages moist, especially in dry climates, improving airflow.
