Casper, an 11-year-old domestic longhair, presented to us with a fast-breathing rate and difficulty breathing. 

He was initially stabilised with oxygen and mild sedative medication. 

Once stable, an ultrasound and x-ray of his chest revealed changes to the lungs. He underwent an anaesthetic for a bronchoscopy and lung wash. Samples of lung fluid ruled out any bacterial or viral infections but showed high numbers of white blood cells consistent with feline asthma/chronic bronchitis. 

Unlike in humans’ asthma in cats is thought to be caused by an allergy or irritation to something in the home or environment but often we do not find the exact trigger. 

The main method of managing asthma in cats is through steroids, these can be given by mouth, or cats can be trained to use an inhaler. It is also important to reduce potential triggers at home including smoke, dust, mould and household cleaning products and for overweight cats to lose weight. 

We are pleased to report that Casper is doing well on his current steroid regime and back to his normal, hungry self!
