Understanding Blastomycosis in Cats
Blastomycosis is a fungal disease that primarily affects dogs and humans, but it can also occur in cats. The disease is caused by the fungus Blastomyces dermatitidis and is commonly found in North America, particularly in the Mississippi, Missouri, and Ohio river valleys, as well as near the Great Lakes, Manitoba, and Ontario.
Causes and Transmission
Cats can acquire blastomycosis through various means. The most common route of infection is through the inhalation of fungal spores present in the environment. These spores are released by the fungus, typically found in moist soil, particularly in swamp-like areas or regions with decaying matter. Cats can also become infected by ingesting or inhaling the fungal spores, or through the direct entry of the organism into the skin via a wound or cut (PetMD).
It is important to note that blastomycosis is not contagious between animals and humans. Cats cannot pass the infection to other animals or people, and vice versa.
Common Symptoms
The signs and symptoms of blastomycosis in cats can vary but commonly involve the respiratory system. Cats infected with blastomycosis may exhibit:
- Coughing
- Difficulty breathing
- Rapid or labored breathing
- Sneezing
- Nasal discharge
- Weight loss
- Lethargy
- Loss of appetite
In some cases, blastomycosis can also affect other organs, such as the skin, eyes, bones, or central nervous system. However, respiratory symptoms are the most frequently observed in affected cats. For a comprehensive list of symptoms, refer to our article on blastomycosis in cats symptoms.

Diagnosis and Prognosis
When it comes to blastomycosis in cats, prompt diagnosis and appropriate treatment are vital for a favorable prognosis. In this section, we will explore the diagnostic methods used to identify blastomycosis in cats and discuss the prognosis and treatment options available.
Diagnostic Methods
Diagnosing blastomycosis in cats can be challenging, as the available diagnostic tools are primarily developed for dogs. However, clinical signs can provide important clues. Common symptoms of feline blastomycosis include difficulty breathing, lethargy, weight loss, fever, cough, ocular changes, neurologic changes, or skin lesions. If your cat exhibits these symptoms, it is crucial to consult with a veterinarian.
To confirm the diagnosis, a veterinarian may perform a variety of tests. Visualization of fungal organisms in infected tissues under a microscope is a common diagnostic method for blastomycosis in cats. However, it is important to note that data on urine and blood tests for blastomycosis in cats is limited.
Prognosis and Treatment
The prognosis for feline blastomycosis is guarded, but it is improving with the availability of newer antifungal medications. Treatment typically involves a prolonged course of oral antifungal medications tailored to the individual cat’s condition. The duration of treatment can range from two to six months.
It is crucial to administer the prescribed antifungal medication consistently and as directed by the veterinarian. Completing the full course of treatment is essential to increase the cat’s chances of recovery and reduce the likelihood of relapse and returning symptoms. Regular follow-up visits with the veterinarian are necessary to monitor the cat’s progress and adjust the treatment plan if needed.
While the prognosis for feline blastomycosis remains guarded, advancements in antifungal medications offer hope for improved outcomes. If you suspect your cat may have blastomycosis, seek veterinary care promptly to ensure an accurate diagnosis and appropriate treatment. Early intervention is key to enhancing the cat’s prognosis and overall well-being.

Prevention and Management
When it comes to blastomycosis in cats, prevention and management play vital roles in ensuring the well-being of our feline companions. Understanding the risk factors and available treatment options is essential for preventing the spread of the disease and providing effective care.
Risk Factors
Cats with compromised immune systems, weak or sick cats, and those receiving long-term antibiotic drugs or immunosuppressive agents are more susceptible to fungal infections such as blastomycosis. It’s crucial to monitor the health of cats with these risk factors closely and take preventive measures to minimize the chances of infection.
Treatment Options
When it comes to the treatment of blastomycosis in cats, a multi-faceted approach is often required. Antifungal medication is the primary treatment method, typically administered daily for two to six months. Following the prescribed medication regimen is crucial to increase the chances of recovery and reduce the likelihood of relapse and returning symptoms.
In some cases, supportive care may be necessary to manage symptoms and support the cat’s overall health. This may include providing appropriate nutrition, ensuring hydration, and addressing any secondary complications that may arise.

It’s important to note that blastomycosis is not contagious between animals and people, but it can be fatal to those infected. However, taking precautions to prevent the spread of the disease among animals is still crucial for the overall well-being of all pets.
By understanding the risk factors and available treatment options, cat owners can take proactive measures to prevent blastomycosis and effectively manage the disease if it occurs. Regular veterinary check-ups, maintaining a clean and healthy environment, and providing proper nutrition and care can go a long way in safeguarding the health of our feline companions.
Blastomycosis in Outdoor Cats
When it comes to blastomycosis, an uncommon fungal infection in cats, outdoor cats are at higher risk, especially those with access to wet environments like streams, lakes, or swamps. The primary cause of blastomycosis in cats is the inhalation of aerosolized spores of the fungus Blastomyces dermatitidis, commonly found in soil around bodies of water (Vetster). Let’s explore the environmental factors and high-risk locations associated with blastomycosis in outdoor cats.
Environmental Factors
The fungus responsible for blastomycosis thrives in warm and moist environments. Outdoor cats are more likely to come into contact with the spores while exploring areas such as river basins or wetlands. These environments provide the ideal conditions for the fungus to grow and release spores into the air. Cats may inhale these spores, leading to infection. It’s important to note that blastomycosis is not directly contagious from cat to cat or cat to human. However, there have been rare cases of infections spreading through dog bites, and the presence of infected cats within a household may indicate potential exposure of humans to fungal spores (Vetster).
High-Risk Locations
Blastomycosis is more prevalent in certain regions, especially those with specific environmental conditions. The areas where blastomycosis is most commonly reported include the river basins of the Mississippi, Tennessee, Ohio, and St. Lawrence rivers. Additionally, it is particularly common in the Southeastern United States. These regions offer the warm and moist environments that support the growth and spread of the Blastomyces dermatitidis fungus. If you live in or near these areas and have an outdoor cat, it’s essential to be aware of the potential risk of blastomycosis.
By understanding the environmental factors and high-risk locations associated with blastomycosis, cat owners can take precautions to reduce the risk of infection. Keeping outdoor cats away from wet environments and monitoring their activities in areas with a higher prevalence of blastomycosis can help minimize the chances of exposure. If you suspect your cat may be showing symptoms of blastomycosis, such as those outlined in our article on blastomycosis in cats symptoms, it’s crucial to seek veterinary care promptly.
