To determine whether a cat has a nasal branch, you can take the cat to a pet hospital or laboratory for PCR examination. Feline rhinitis is the herpes virus in cats. When infected, symptoms such as sneezing, runny nose, watery eyes, depression, loss of appetite, and weight loss will occur. ​​​​​​

The main route of infection of feline herpes virus is through contact between susceptible cats and infected cats. After infection, the virus will be carried and excreted to the outside world for life.

Feline rhinophyma is contagious from cat to cat. The initial symptoms include sneezing, watery eyes, and runny nose. It should be noted that when a cat has a cold, the nasal discharge is often clear and sneezing, while the nasal branch will have thick nasal discharge, even red eyes, frequent tears, and conjunctivitis. For safety reasons, the affected cat needs to be isolated first. It can be kept in a separate cage or placed in a separate room. Do not let other cats come into contact with the affected cat.
