why does my cat keep sneezing

Cats sneeze for several reasons, often related to irritation or infection in their nasal passages. Common causes include allergies (to dust, pollen, mold, or food), upper respiratory infections (often viral like feline herpesvirus or calicivirus), bacterial or fungal infections, exposure to chemical irritants (such as cleaning products or smoke), foreign objects lodged in the nose, and dental issues that affect nearby nasal areas. Sneezing due to these causes may be accompanied by other symptoms like nasal discharge, coughing, lethargy, or loss of appetite. If sneezing persists, worsens, or is accompanied by concerning symptoms such as nasal discharge (especially colored or bloody), poor appetite, or breathing difficulties, it is important to seek veterinary care. In brief, your cat might keep sneezing due to allergic reactions, infections, irritants in the environment, or underlying dental problems, all of which can irritate the nasal passages and trigger sneezing reflexes.
