We cat lovers are comforted by the purring and the familiar meows from our favorite feline friends. But, it’s the sound of troubled breathing in your cat that makes you sit up and take notice — you want to know what is happening and how to help your cat.

In this article we’ll explore breathing difficulty (dyspnea) in cats. We’ll tell you about the symptoms to watch for, what causes breathing difficulties, and when to seek urgent care at a VEG animal hospital near you.

Understanding your cat’s breathing difficulties

Is your cat having trouble breathing? Before we can understand the cause, it’s important to first understand what kind of breathing difficulty your cat is having.

Heavy, Rapid or Fast Breathing

A cat breathing fast or heavily can be a sign of stress, pain, overheating, or an underlying medical emergency. While the normal breathing rate for cats is typically 20-30 breaths per minute at rest, rapid breathing that continues while your cat is calm should be evaluated by a vet.

Open-Mouth Breathing

Cat open-mouth breathing is almost always abnormal and can signal serious breathing difficulty or distress. If you’re wondering, “Why is my cat breathing heavy with their mouth open?”, it’s important to seek vet care right away.

Labored Breathing

Cat labored breathing may look like exaggerated chest movements, flared nostrils, or visible effort with each breath. Difficulty breathing in cats can be caused by conditions affecting the lungs, heart, or airways and should never be ignored.

Noisy Breathing

Cat noisy breathing - including wheezing, snoring, raspiness, or high-pitched noises - can happen when the airways are partially blocked or inflamed. Changes in your cat’s normal breathing sounds may point to respiratory infections, asthma, or other underlying health issues.

Abdominal Breathing

If your cat’s stomach is visibly moving in and out while breathing, this may be a sign of abdominal breathing or severe respiratory distress. Cats with shallow breathing, heaving, or intense belly movement while breathing should be seen by a vet as soon as possible.

5 common causes for breathing difficulties in cats

Breathing difficulties in cats can happen for many different reasons, ranging from mild respiratory infections to life-threatening emergencies involving the heart or lungs. If your cat is breathing heavy, fast, or showing signs of labored breathing, understanding some of the most common causes can help you recognize when it’s time to seek urgent veterinary care.

1. Heart disease can cause difficulty in breathing

Difficulty in breathing due to decreased oxygen flow or fluid accumulation in or around the lungs are symptoms of heart disease in cats. One common heart-related condition in cats is hypertrophic cardiomyopathy (HCM), the thickening of the heart muscle, which impedes normal heart function.

2. Asthma in cats can contribute to difficulty breathing  

Just as it is for humans, feline asthma is an inflammatory condition which affects the small passageways in the lungs. Symptoms include:

• Wheezing

• Coughing

• Difficulty breathing

How to manage asthma in your cat.

While the symptoms of asthma are not curable, they are manageable under the supervision of your VEG emergency vet. Treatment may involve medication to reduce lung inflammation/dilate the airways and make breathing easier for your furry family member.

3. Respiratory infections in cats

Conditions such as feline upper respiratory infections (URI) are common in cats and may severely impact their breathing. Usually caused by viruses or bacteria, symptoms include:

• Coughing

• Nasal discharge

• General malaise

• Sneezing

• Decreased appetite

Importance of early treatment for respiratory infections.

Any respiratory distress in your cat should be treated as an emergency. Spotting these signs in your cat and getting early treatment for respiratory infections can prevent complications and lead to a speedier recovery. Our vets at VEG can provide the medications and care needed to fight the infection and relieve the symptoms.

4. Pleural effusion

The accumulation of fluid in the space around the lungs, called pleural effusion, can cause your cat to struggle to breathe.

Pleural effusion in felines can stem from various health issues, including:

• Heart failure

• Chest trauma

• Tumors

If you think your cat may have pleural effusion, it’s best to seek urgent veterinary care at VEG right away. Our experienced emergency vets will triage your pet immediately. We may need to perform a procedure to remove the fluid and diagnose the underlying cause to treat it appropriately.

5. Lung tumors in cats

Although not nearly as common, lung tumors can be a serious cause of respiratory distress in cats due to the restriction of airflow or accumulation of fluids. Fungal disease can also cause difficulty breathing in cats and can sometimes look like cancer on x-rays. If you suspect your cat has a lung tumor or fungal disease, they need to be assessed by our emergency vet, treated, and monitored.

Treatment options depend on the type and stage of the tumor and may include:

• Surgery

• Chemotherapy

• Palliative care

When to seek emergency vet help if your cat is not breathing easily

The following symptoms, especially in middle-aged and older cats, may indicate heart disease or respiratory disease when combined with breathing problems. It’s best to contact your emergency VEG vet right away if you notice:

• Lethargy

• Reduced appetite

• Sudden onset of heavy breathing
