Feline Asthma

Feline asthma is the most common lung disease of cats. It is found in about 1% of cats.  Up to 5% of cats with asthma are siamese.  It is found in young to middle aged cats. I

It is also called feline allergic bronchitis.  The most common symtoms are coughing and wheezing.  The wheezing form is more dangerous and life threatening.  These symptoms are an emergency.  They have trouble getting air in and out of their lungs  because the bonchioles are constricting.  These cats may have an incrased respiratory rate and may be breathing through their mouths.  If the cats are just coughing and otherwise acting OK, it is not an emergency.  The bronchioles in both forms have a lot of mucous plugging the airways. black cat Sometimes owners think their cat has a hairball or is trying to vomit.  

To diagnose asthma, x-rays are very helpful.  They can show evidence of thickening bronchi called doughnuts or tram lines.  Some cats with asthma may have normal looking lungs on x-ray.  Some have overinflated lungs and the diaphragm may be flattened.  Most are not infected, but about 25% may also have a bacterial infection called mycoplasma and will need antibiotics also.  Some will have a collapsed right middle lung lobe because of mucous plugging.  blood tests may reveal an elevation of allergy cells called eosinophils in about 20% of cases.  Feline Heartworm disease can cause some of the same symptoms and so a heartworm test should be perfomed.  

Treatment of asthma involves using corticosteriods and bronchodilators.  If they are in an emergency, such as experiencing wheezing and difficulty breathing, injectable bronchodilators and steriods are used along with oxygen therapy.  The cats are then put on oral prednisolone and the dose is tapered to give the lowest dose possible to keep the symptoms at bay.  An alternative treatment is the inhaler steriod "Flovent".  A spacer chamber with a face mask called "Aerocat" can be used to put steriods directly into the lungs.  This has fewer side effects over the long term for the cats but it takes about 2 weeks to start working.  The inhaler is compressed into the chamber and the cat breathes into it for 7-10 breaths.  Many cats can be trained to use the spacer.  Emergency bronchodilators can be given this way also.

Causes of asthma are usually not found.  They can be allergies to pollen, cigarette smoke, dust, dust mites, molds and others.  Feline asthma is a serious disease and can be life threatening.  

Feline Idiopathic Cystitis

Feline idiopathic cystitis, formerly called FUS and FLUTD is a poorly understood condition in cats, which unfortunately is pretty common and

has a tendency to recur. In fact, about half of the cats with this condition will have at least another episode within a year.


Some or all of the following symptoms may be observed: yellow cat


bloody urine

excessive licking of the urinary opening

straining to urinate

frequent visits to the litterbox or urinating outside of the litterbox

vocalizing in pain while inside the litterbox

inability to urinate due to a blockage of the urethra


Your veterinarian will want to conduct a urine test and take radiographs, to rule out a blockage, a bladder infection and bladder stones.

Only when all these other conditions are ruled-out, a diagnosis of FIC can be made.

Not one single cause has been identified, but environmental stress and concurrent illnesses seem to play an important part. Younger cats seem to be predisposed to this disease.  

The reason why only some cats get it, seems to have to do with the way that they handle stress, and the hormones associated with it. A cascade of events is triggered that leads to  

irritation of the bladder lining, pain, bleeding, and urgency to urinate.

Caring for Our Mature Adult and Senior Feline Companions: “Doctor, is this just old age?”

Sometimes as we see little changes in our mature adult and senior cats, we are tempted to attribute those changes to simple aging.  Old age is not necessarily a disease, however.  In fact, many conditions or changes that our older cats go through can be diagnosed and treated appropriately, adding high quality to our feline companion’s lives.   Below are common issues in our older cats and a brief explanation of what can be done to further explore, diagnose, and sometimes treat these issues:cat


Weight loss or changes in appetite:

Is your kitty looking a lot thinner lately?  Can you feel or even see the shoulders, spine, or hips, but couldn’t before? Unexpected, unintentional weight loss in your cat should always be discussed with your veterinarian.   Eating less (or more, but accompanied by weight loss) is a flag for us to start with an exam and lab work to rule out common senior feline diseases, such as diabetes, hyperthyroidism, and kidney disease.  Conditions that affect the liver, pancreatitis, inflammatory bowel disease, or other primary or secondary gastrointestinal diseases should also be ruled out—sometimes we can diagnoses these issues through lab work and x-rays. Other times more advanced diagnostics such as x-rays, ultrasound, or endoscopy are required.   Dental disease is another common issue for mature adult and senior cats and an exam should be done to make sure there are no signs of periodontal disease that would lead to weight loss or a decrease in appetite.
