April is Heartworm Awareness Month. This is the purrfect time to talk about something that doesn’t get nearly enough attention in the world of feline health: heartworms in cats. Heartworms are more often associated with dogs. However, cats are not immune. In fact, heartworm disease in cats can be sneaky, and by the time symptoms show up, it might be a bit too late for effective treatment. In this article, a local Treasure Coast, FL vet explains what heartworms are, how they affect cats, and most importantly, what you can do to protect your precious kitty.

What Are Heartworms, Anyway?

Heartworms are parasitic worms transmitted through mosquito bites. Here’s how it works: When a mosquito bites an infected animal (like a dog or another animal already carrying heartworms), it picks up tiny baby heartworms called microfilariae. When that mosquito bites your cat, those microfilariae are passed on to your kitty, who then becomes a host for the worms.

Now, before you panic—don’t! While heartworms are serious, they are preventable and the chances of transmission can be easily managed with the right care.

Why Are Heartworms Dangerous for Cats?

You might be thinking, “If heartworms are a bigger problem for dogs, why should I worry about my cat?” Well, even though cats don’t usually develop as many worms as dogs, heartworms are still incredibly dangerous for them. The worms can cause inflammation, blockages, and even damage to the heart, lungs, and blood vessels.

In fact, heartworms can cause a condition known as heartworm-associated respiratory disease (HARD) in cats, which affects the lungs and can lead to severe breathing problems. This is why even one of these worms can be potentially life-threatening to Fluffy.

Symptoms of Heartworm Disease in Cats

Because cats aren’t the ideal host for heartworms, the symptoms may be subtler or harder to detect than in dogs. But the key takeaway here is that even just a few heartworms can cause serious health issues in your cat. Cats may not have the same visible signs of infection as dogs, but if left untreated, the disease can still be fatal.

Here are the most common symptoms of heartworm disease in cats:

• Coughing: A dry, persistent cough that doesn’t go away could be a sign of heartworm disease. 
• Wheezing: As heartworms affect the lungs, your cat might start to wheeze or have trouble catching their breath. 
• Difficulty breathing: If your cat is panting or breathing heavily even without exertion, it could be related to heartworms. 
• Lethargy: Cats are usually known for their love of naps, but if your cat suddenly seems more tired than usual, this could be a red flag. 
• Vomiting: Some cats with heartworm disease may throw up. 
• Sudden collapse or seizures: This can happen in very severe cases, often when heartworms block blood flow to critical areas. 

If you notice any of these symptoms, consult with your vet immediately. The earlier heartworm disease is detected, the better the chances of managing it successfully.

Diagnosis: How Do We Find Out if My Cat Has Heartworms?

Diagnosing heartworm disease in cats can be tricky. In addition to blood tests, your vet might need to perform a combination of diagnostic procedures, such as:

• X-rays: These can help identify lung changes that might be associated with heartworm disease. 
• Ultrasound: In some cases, an ultrasound of the heart may be necessary to look for signs of heartworm presence. 
• Electrocardiograms (ECG): This test measures the electrical activity in the heart and can sometimes help detect irregularities caused by heartworm infection. 

It’s worth noting that heartworm disease in cats is often misdiagnosed as asthma, allergies, or other respiratory issues. That’s why it’s so important to get a professional diagnosis.

Heartworm Prevention for Cats

Luckily, preventing heartworm disease is simple. The key is keeping your cat on a regular heartworm prevention schedule. There are several options available, including:

• Oral medications: These are pills or chewables that you give Fluffy, usually each month. 
• Topical treatments: These are applied to your cat’s skin and are absorbed into the bloodstream. 
• Injectable medication: There are also long-acting injectable options that provide heartworm protection for a full year.
  

Even if your cat is an indoor kitty, you should continue with heartworm prevention. Mosquitoes are sneaky and can easily find their way indoors. A single mosquito bite can be all it takes to start an infestation.

Is There a Treatment for Heartworm Disease in Cats?

Unfortunately, there’s no simple cure for heartworm disease in cats. There’s no approved medication that can kill heartworms in cats. In most cases, treatment is focused on managing symptoms and providing supportive care.

In severe cases, your Treasure Coast, FL vet might recommend hospitalization for closer monitoring.

Final Thoughts

Heartworm disease in cats is a serious and potentially fatal condition, but it is preventable. By staying up to date with your cat’s monthly heartworm prevention and paying attention to any signs of illness, you can keep your kitty safe and healthy for years to come.
