Lungworms can pose significant risks to your beloved cat. These parasites have the ability to migrate and find their way into the lungs, causing potential harm. While they are less prevalent compared to intestinal worms, lungworms should not be overlooked. It is important to be aware of key information about lungworms in cats and take necessary measures to ensure your cat's well-being. Here are some essential points to consider in dealing with lungworm infections and helping your cat regain good health.
What is lungworm?
Lungworms are parasitic organisms that rely on their hosts for survival and reproduction. While you may be familiar with lungworms in dogs, it's important to note that they do not commonly affect cats. Cats, however, can still be affected by lungworms, specifically two types: Aelurostrongylus abstrusus (feline lungworm) and Capillaria aerophilus (bronchial capillarid, which affects both cats and dogs). These parasites have the potential to cause damage to the lungs.
So, how do cats become infected with lungworms?
Outdoor cats have a higher risk of exposure as lungworms typically need to go through a food chain before reaching their feline host. Cats can become infected when they consume water or prey that is carrying the larval stage of the worm.
Once inside the cat's body, the larvae migrate from the intestines through the bloodstream to the lungs, where they develop into adult worms and lay eggs within approximately 40 days. These eggs are then either coughed up or passed in the cat's feces. Birds, rodents, or snails may eat the eggs, continuing the lifecycle.
Identifying lungworm infection in cats can be challenging, as the symptoms can mimic other conditions. If you observe persistent coughing or difficulty breathing in your cat, it is essential to consult with your veterinarian. Other signs of lungworm infection may include lethargy and a lack of interest in play. If your cat's behavior seems off or unusual, scheduling an appointment with the vet is advisable.
How is lungworm in cats diagnosed?
When you visit the vet with concerns about lungworm in your cat, they will begin by asking about the symptoms you have observed. To determine if your cat has been infected with lungworms, they may conduct a series of diagnostic tests, which could include:
- Blood tests
- X-rays to assess the condition of the lungs
- Bronchoscopy to examine the cat's airways
- Testing the cat's feces for the presence of larvae
Should you worry if your cat has lungworms?
Generally, lungworm infection in cats is not life-threatening. However, if your cat's immune system is weakened and unable to effectively fight off the parasite, the infection can become more serious. This is especially true for kittens or senior cats, as well as cats with pre-existing conditions that compromise their immune system. Unfortunately, the most vulnerable kittens are also the most susceptible to lungworm infections. It is crucial to seek professional advice from your vet and closely follow the recommended treatment plan.
What is the treatment for lungworm in cats?
Once the infection is diagnosed, the vet will likely prescribe a suitable parasiticide such as Fenbendazole, Albendazole, Ivermectin, Praziquantel, or Levamisole. Typically, a 10-day course of Fenbendazole along with three to four days of Ivermectin is effective in clearing the infection. In severe cases where secondary infections like pneumonia have developed, a course of antibiotics may also be prescribed.
After completing the prescribed treatment, a generally healthy cat should recover within a couple of months.
Is there a way to prevent lungworm infection in cats?
There are several measures you can take to prevent lungworm infection in your cat. Ensure that your cat receives regular deworming medication as recommended by your vet to minimize the risk of lungworms gaining a foothold. Additionally, engaging your cat in stimulating indoor games and activities can help reduce the chances of them encountering infected prey. By providing mental and physical stimulation indoors, you can decrease the likelihood of your cat using an infected animal as a plaything.
