If your cat has been coughing in short, harsh bursts — almost as though something were stuck in its throat — you are not alone in feeling worried. This unsettling sound can easily be mistaken for a hairball episode, yet it may point to a deeper respiratory issue. Feline asthma affects a surprising number of household pets, and understanding the signs early can make all the difference.
Why that persistent cough deserves your attention
Many owners first notice a strange posture: the animal crouches low, extends its neck, and produces a dry, repetitive cough. At first glance, this looks like a routine attempt to expel a hairball. However, when the episode ends without producing anything, it should raise a red flag.
Feline asthma is a chronic inflammatory condition of the lower airways. According to veterinary estimates, it affects roughly 1 to 5 percent of domestic cats worldwide. The inflammation narrows the bronchi, making each breath harder and triggering those alarming coughing fits.
Certain breeds, such as Siamese, appear more predisposed, though any cat can develop the condition. Age at onset varies widely, but most diagnoses occur between two and eight years old. Because symptoms come and go, some owners wait months before consulting a veterinarian — a delay that can allow the disease to progress silently.

Common triggers hiding inside your home
Asthma flare-ups in felines are often provoked by airborne irritants. Dust from clay litter, cigarette smoke, scented candles, and aerosol sprays rank among the most frequent culprits. Even seasonal pollen drifting through an open window can set off an episode.

A change in routine, a new pet in the household, or construction noise can heighten airway reactivity. By identifying and reducing these triggers, many owners see a noticeable drop in the frequency of attacks. Keeping the living space well ventilated, yet free from harsh chemical odours, is a practical first step.
- Clay litter dust — switch to a low-dust or paper-based alternative
- Tobacco smoke — avoid smoking indoors at all times
- Scented household products — opt for fragrance-free cleaners
- Mould and mildew — control humidity below 50 percent
- Pollen exposure — keep windows closed during peak pollen hours
How veterinarians diagnose feline asthma in 2026
Diagnosis typically begins with a thorough physical examination and a detailed history of symptoms. The veterinarian will listen to the lungs with a stethoscope, searching for characteristic wheezing or crackles. This initial check often reveals increased respiratory effort even when the animal appears calm.
Chest radiographs remain the most widely used imaging tool. In an asthmatic cat, X-rays frequently show a distinctive “doughnut” pattern caused by thickened bronchial walls. Air trapping in the lungs, visible as hyperinflation, further supports the diagnosis. In some cases, a bronchoalveolar lavage — a procedure that collects fluid from the airways — is performed to confirm the presence of eosinophils, a type of white blood cell linked to allergic inflammation.
Advanced clinics may also offer computed tomography scans for complex cases. Still, for most pets, standard X-rays combined with clinical signs provide a reliable answer. Early and accurate diagnosis helps prevent irreversible airway remodelling, so prompt testing is strongly encouraged.
Blood work and faecal analysis are often included to rule out other conditions. Lungworm infection, for instance, can mimic asthma symptoms almost perfectly. By eliminating these look-alikes, the veterinarian ensures the treatment plan targets the actual problem.
Treatment options that help your pet breathe easier
The cornerstone of therapy involves inhaled corticosteroids delivered through a specially designed feline spacer device. This approach targets inflammation directly in the lungs while minimising systemic side effects. Most animals adapt to the spacer within a few days, especially when introduced gradually with positive reinforcement.
During acute crises, a bronchodilator — often albuterol — provides rapid relief by relaxing constricted airway muscles. Veterinarians sometimes prescribe oral corticosteroids for the initial stabilisation phase, then transition to the inhaled form for long-term management. Each treatment plan is tailored to the severity of the disease and the individual animal’s response.
Regular follow-up visits, typically every three to six months, allow the care team to adjust dosages and monitor lung health. Owners play an active role by tracking coughing frequency at home and reporting any changes promptly. With consistent management, many affected pets enjoy a good quality of life for years.
Living with an asthmatic cat — daily habits that matter
Consistency is key once a diagnosis is confirmed. Administering medication at the same time each day helps maintain stable drug levels in the airways. Skipping doses, even when the animal seems fine, risks triggering a rebound flare-up that can be harder to control.
Weight management deserves attention as well. An overweight cat faces added pressure on its respiratory system, which can worsen symptoms. A balanced diet, portion control, and gentle play sessions keep body condition in check without stressing the lungs. Your veterinarian can recommend a calorie target suited to your pet’s needs.

Vacuuming with a HEPA-filter machine, washing bedding weekly, and using air purifiers in key rooms all contribute to cleaner indoor air. These small adjustments, sustained over time, create a safer breathing environment for a sensitive feline.
Monitoring technology has grown more accessible in 2026. Wearable activity trackers designed for pets can flag changes in resting respiratory rate, alerting owners before a full-blown crisis develops. While no gadget replaces professional veterinary care, these tools add a helpful layer of early detection to your daily routine.
