Signs of asthma in cats can vary in severity and may be constant or come and go:  

• Persistent coughing (often in short bouts, like your cat is trying to be sick) 

• Fast breathing/open-mouthed breathing or panting (can occur after exercise eg, playing) 

• Noisy breathing and wheezing 

• Difficulty in breathing  

Contact your vet if your cat is coughing or showing any signs of breathing problems, such as his/her chest moving very rapidly, breathing with his/her mouth open, or making noises when breathing in and out.  

If you think your cat may be having an asthma attack, this is an emergency, your cat must be seen by your vet urgently.   

History and physical exam by your vet. It’s helpful if you can bring a video of abnormal breathing or coughing  

Your vet may advise further tests such as:  

• Blood test 

• Examining the throat under an anaesthetic and x-rays 

• Endoscopy (camera down into lungs to look up)  

• Airway washes (BAL), collecting cells and fluid from the airways to examine under the microscope  

• Testing of faeces (for lungworm which can cause coughing)  

• Steroids to reduce inflammation  

• Bronchodilators to relax the muscles in the airways, making it easier to breathe  

• Inhalers, like those used in humans, can deliver medication directly to the lungs  

• Minimise allergens and irritants  

• Manage stress by creating a calm environment and use of pheromone diffuser  

• Maintain a healthy weight  

• Regular monitoring of your cat's breathing effort and seeking veterinary attention for any concerning symptoms is essential  

The prognosis for cats with asthma is generally good with appropriate treatment and management, but it is not curable and requires lifelong care. While some cats may experience severe attacks that can be life-threatening, many asthmatic cats live happy, active lives with proper management.
