What are the symptoms of a respiratory infection in cats?

A feline respiratory infection usually shows as sneezing, labored breathing, nasal discharge, increased eye discharge, open-mouth breathing, loss of appetite, wheezing, and coughing. If you notice these signs, take the cat to a veterinary hospital promptly for examination and targeted treatment based on the specific cause, and to rule out viral infection, since viruses such as feline herpesvirus and calicivirus also cause respiratory symptoms. Because respiratory infections can easily lead to secondary lung infection, the affected cat must be treated promptly to prevent complications.
