Some cats with nasal allergies may have a clear, dripping discharge from their nostrils, but this can be difficult to spot if the cat regularly licks it away. If you see nasal discharge, look closely to see if it comes from one, or both nostrils. A bilateral discharge (from both sides) is more likely to be caused by an infection or allergy, while a unilateral (one sided) drip could be caused by a foreign body, or infection in one side of the nose.

If you notice that your cat sneezes a lot, you will need to schedule an appointment with your vet to determine the cause. It might be allergies or an infection, but your veterinarian will have to test your cat’s mucus to be sure.

The most common cause of nasal and sinus congestion are viral infections. These viruses include feline herpesvirus (FVR) and feline calicivirus (FCV). These infections also cause swollen, red, and runny eyes along with mouth ulcers and salivation. You can help protect your cat from these viruses by keeping your cat’s vaccinations up-to-date and keeping your cats away from any cats that seem sick. The recurrent viral illnesses in cats suppress your cats immune system so that secondary, opportunistic and very damaging bacteria invade the area and cause more severe disease, discharge, and lack of appetite. Realize also that many times your kitty has ‘cleared’ the viral illness, but the more ‘difficult to clear’ bacterial invaders remain. This is why it is vital that you have your pet checked by a licensed veterinarian if any of the above symptoms occur. These conditions cause breathing difficulties because of the mucus that builds up in your cat’s nose. Just like people with a heavy cold, the mucus blocks the nasal passageways and makes it difficult to breathe.

There is a certain amount of leeway in the normal respiratory rate range, for instance a cat taking 32 breaths a minute, who is otherwise perfectly well, is not considered abnormal. [4] X Research source You should, however, become concerned if you notice that your cat’s breathing rate is around 35 to 40 breaths per minute, or if her breathing is labored.

To determine if your cat is breathing normally, it is best to fix your gaze on one spot (perhaps a whorl of fur on her chest) and watch as it moves slowly up and down. Her belly muscles should not be involved in filling her chest with air. If her tummy expands and contracts as she breaths, this is abnormal. If her chest “heaves” and makes exaggerated, easy to see, in-out breathing movements, or her belly moves in as she breathes, this is abnormal.

A cat in this position may also open her mouth and begin to pant.

Cats may also pant when they are anxious or frightened, so consider your cat’s environment as well.

If the vet suspects the infection is viral then antibiotics may be of no help. Likewise, if antibiotics are prescribed, it may take four to five days before the infection improves, so in the meantime you can help to ease your cat’s breathing in other ways.

Take the cat into the bathroom and shut the door. Switch the shower onto hot and draw the shower screen so that there is a solid barrier between the cat and the hot water. Sit in the steamy atmosphere for 10 minutes at a time. If you can do this two to three times a day, your cat should be able to breathe a little easier.

If the cat has a heavy nasal discharge then wiping the nose regularly can really help make your cat more comfortable.

This is a drug, such as Bisolvin, which breaks down mucus and helps it to liquefy. The active ingredient in Bisolvin is bromhexine. When the mucus thins, your cat will have an easier time sneezing it out. Bisolvin comes in 5 gram (g) sachets and can be mixed in food once or twice a day. The dose for a cat is 0. 5 g per 5 kg of body weight. This translates as a “generous pinch” from the sachet, once or twice a day on food. [10] X Research source

If you think your cat has chest congestion, do not try home remedies; delaying your cat’s visit to the vet may only make her condition worse.

Intense antibiotics are generally prescribed to treat pneumonia. If your cat is very sick, she may also need supportive care, such as intravenous fluids or an oxygen tent. [11] X Research source

If heart disease is to blame for your cat’s difficulty breathing, your veterinarian will try to determine the type of heart disease and prescribe the right medications. Cats often require oxygen therapy to help stabilize them before any type of medicine or other treatments can be administered.

For asthma, many cats are prescribed corticosteroids, either by a depot inject or in oral tablet form. Steroids are powerful anti-inflammatory medications that work to reduce inflammation in your cat’s airways. However, salbutamol inhalers are also available for asthmatic cats – if the cat tolerates the face mask. Bronchitis is also treated either with steroids, or a bronchodilator, which is a drug that stimulates the stiff airways to open up.

Lungworms can be treated with anti-parasite drugs such as ivermectin or fenbendazole.

Tumors take up space in the chest and compress the lungs or major blood vessels. Solitary tumors may be surgically removed, but on the whole the outlook for a cat with lung tumors is poor. Talk to your vet about options. [13] X Research source

This fluid can put pressure on your cat’s lungs, which in turn cause them to collapse. Because of this, they cannot expand fully, making your cat feel short of breath. If your cat is having great difficulty breathing, the veterinarian may drain the fluid off using a special thoracic needle. Removing the fluid allows the lungs to re-inflate and gives temporary relief. However, the fluid will return unless the underlying problem is treated.
