Feline strongyloidiasis is characterized by respiratory tract infection. Strongyloides felis usually lives on the septal lobes of cats' lungs, and weak cats and kittens are susceptible to infection. Generally, the infection rate is higher in cats that roam freely.

Cats with mild infection have no obvious symptoms and only show an increase in respiratory mucus. It is generally not harmful to cats in good physical condition. However, in weak cats, it can easily cause secondary bacterial infection and cause pneumonia. ​​​​​​

Severely infected cats and kittens may have clinical symptoms of coughing and difficulty breathing, and when complicated by pneumonia, their body temperature will rise.

In mild infections, no treatment is required because the adult worms can be shed naturally. For cats with severe infection, tetramidazole can be used to deworm, and Haiqunsheng can be used as preventive medicine.

If domestic cats are not used for breeding, they should be castrated to prevent cats from often running outdoors during the estrus season and contacting infectious sources. Keep the cattery clean and dry to prevent the growth of intermediate hosts of the disease.
