Symptoms of rhinitis in cats

Rhinitis is a nasal cavity inflammation. The nasal region, which starts in the nostrils that we can see from the outside, continues into the nasal cavity, which occupies what we see from the outside as the muzzle, and extends to connect with the throat and sinuses. Their inflammation is called sinusitis and it is common to occur in rhinitis, as well as other problems in the respiratory tract or ear, because of the connection that all these systems have.
