Final answer:
Cats that are most prone to upper respiratory aspergillosis are those that have weakened immune systems, such as cats with Feline Immunodeficiency Virus (FIV) or Feline Leukemia Virus (FeLV). Aspergillosis is caused by the fungus Aspergillus, which can be found in soils and organic debris. Symptoms can include shortness of breath, wheezing, coughing, runny nose, and headaches.
Step-by-step explanation:
Cats that are most prone to upper respiratory aspergillosis are those that have weakened immune systems, such as immunocompromised cats. This can include cats with Feline Immunodeficiency Virus (FIV), Feline Leukemia Virus (FeLV), or cats undergoing certain medical treatments.
Aspergillosis is commonly caused by the fungus Aspergillus, which is found in soils and organic debris. Inhalation of spores can lead to respiratory infection. Symptoms can include shortness of breath, wheezing, coughing, runny nose, and headaches.
It is important to note that while cats with weakened immune systems are more prone to aspergillosis, the infection can occur in any cat if exposed to high levels of the fungus.
