Cats, Asthma and Care

Asthma in cats is becoming a more and more common condition. Usually, cats may develop asthma when they are adults, somewhere between two to eight years old.

How can you recognize the symptoms of asthma in your cat? What can cause asthma in cats? How can you offer the best care to your kitty that has asthma? We answer all these questions below.

What Can Cause Asthma in Felines?

Although feline asthma has been a bit of a mystery to the world of medicine, it is clear that it reacts to certain allergens like harsh cleaning products, the smell from deodorants, pollen, smoke from cigarettes, and dust from cat litter.

Moreover, the stimuli (the allergens) cause the airways to narrow down, thus restricting the lungs to get airflow. Both the inflammatory reaction and the contraction of the surrounding muscles are the cause for the bronchi to start narrowing down. When it comes to felines, there is even less airflow in their lungs due to their immune system causing excessive mucus to be produced in the bronchi.

Asthma develops when there is constant exposure to allergens which cause the cat’s immune system to form a chronic response to them.

How Can You Recognize the Symptoms of Asthma in Your Cat?

Luckily, symptoms in felines are fairly easy to notice. If one or more of the following symptoms have been occurring regularly, then it’s time to take your feline friend to the vet:

  • Coughing
  • Wheezing
  • Vomiting (especially mucus)
  • Rapid breathing
  • Breathing through the mouth

The most important thing to do if you notice any of these symptoms is to visit your veterinarian. They will run tests to confirm the condition of your kitty.

The degree to which these symptoms develop can vary. Not all cats will show a high-intensity of asthma symptoms, so be observant. Coughing and wheezing are the two most common symptoms that you may notice. But, they may not appear frequently, and also they may be symptoms of other conditions. That’s why a vet visit is a must.

If your feline companion is having an asthmatic attack, it will extend its neck while attempting to lower its body to the ground. However, with intense attacks, it will cough, trying to gasp for breath and gag like it would when vomiting a hairball.

How Can You Offer the Best Care to Your Kitty that has Asthma?

As mentioned above, the first thing you need to do in order for your kitty to get the best care it deserves is to take it to the vet. After confirming its condition, the next easiest step is to get the best dust-free cat litter for asthma.

Furthermore, removing any triggers that can cause respiratory problems for your cat or yourself is something that you should do even if your kitty doesn’t suffer from asthma. The allergens can cause the development of not only asthma but a number of other respiratory problems.

Actions like burning scented candles, deodorizing your room with products that contain artificial fragrance, frequently smoking indoors, using strong cleaning products that have harsh chemicals, regularly using your fireplace, and using perfumes and hairsprays around your kitty all these are triggers and can cause an asthma attack in your cat.

The best care for cat

Now you know what you should avoid doing to protect your feline friend. But, there are some things you may want to consider doing and paying attention to in order to manage your cat’s condition better.

Regular vet visits and check-ups for parasites are crucial for your kitty’s overall health. Furthermore, if your cat has put some weight it may make its breathing more difficult. So, ensure your kitty is at its appropriate and healthy weight.

We mentioned that pollen can be yet another trigger for asthma. One thing you can do is avoid letting your cat go outdoors during the pollen production season.

Stress is another thing you need to pay attention to. Observe and notice what can be stressing your cat, and eliminate it.

Best dust free cat litter for asthma – it’s all about the material

Choosing the best dust-free cat litter for asthma may not be so difficult after you go through our short guide.

When making a decision, the most important feature to take into consideration is the material of which the litter is made.

Cat litter made of clay is the number one in producing dust clouds. Although their clumping characteristic may be preferred by many cat parents, the dust from the clay can cause serious respiratory issues. Unless it is specifically stated that it is dust-free, it is definitely one to avoid.

Silica gel crystal litter may look like a safe choice because it has highly absorbent qualities, but its dust, no matter how small, can be very toxic to your cat when it builds up in its system.

Cat litter made of natural material like wood pellet cat litter or walnut shell litter can be safer than the previous two examples. But there are still certain qualities to consider. Even natural litters can produce dust, so it is extremely important to check how much dust is and what the characteristics of the dust are. Furthermore, artificial fragrances worsen asthma conditions in cats and people, so opt for fragrance-free litter.
