A few people recently asked whether it was normal for a cat to pant. We figured that if there's a few people asking about panting, then there’s likely a whole lot more that have wondered, too.

So here’s the “skinny” on panting in cats…

Panting may be a normal response for a cat that has just exercised or exerted itself (think serious laser pointer session, or running around with another of the family pets). It may also be a normal response for a stressed cat (think car trip, or visit to the vet). And it may be a normal response for an overheated cat (think no air conditioner on a warm day).

There are quite a few conditions that can be associated with panting in cats. If a cat’s panting happens often and isn’t always clearly associated with exercise/exertion, stress, or increased environmental temperatures, then there’s a far greater chance that the panting is a result of one of these conditions:

  • Pain
  • “Thyroid storm” associated with undiagnosed or uncontrolled hyperthyroidism
  • Congestive heart failurehypertrophic cardiomyopathy is one of the most common types of heart disease in cats
  • Pyothorax — infection within the chest cavity, surrounding the lungs
  • Pleuritis — inflammation of the lungs
  • Fever/Hyperthermia — from an infection, cancer, or another problem
  • Central Nervous System (think “brain”) diseases can cause panting — incl. trauma, tumors, infections, and others.
  • Conditions resulting in “acid-base imbalances” — including diabetic ketoacidosis, and urinary obstruction (panting can result from the acid-base imbalance, as well as the pain and abnormal heart rhythms associated with a blocked urinary tract)

When you’re in doubt or concerned about your cat’s panting episodes, you should always check with a veterinarian. Many of the conditions listed above can deteriorate rapidly, and some can even be quickly fatal. Fortunately, several can be well managed when caught and treated early enough.

Cats Panting – Some Examples

Here's a cat that's panting during a good romp with a feather toy. He starts really panting about :50 seconds into the video.

 

Here's a cat panting from, most likely, the stress of being in the car and over-heating.
(BTW: A cat being loose in the car is not something we recommend - it's not safe... for anyone!)

 

I hope this helps to answer a question that you may have been wondering about. If you're concerned please bring your cat to see your veterinarian.
