Yes, allergies can cause chronic sneezing in cats. The cause is allergic rhinitis, inflammation of the nasal lining that brings sneezing and watery discharge. The Merck Veterinary Manual lists this pattern in cats in its guide to atopy in cats. Timing, triggers, and other signs help sort allergy from infection.

What does allergy sneezing look like?
Allergy sneezing often comes with clear, watery nasal discharge. Fits may repeat over days or weeks rather than stop after one irritant. Cornell dermatology chief William Miller links inhalant allergy to sneezing and watery eyes, as noted in a Cornell CatWatch report.
Skin stays the main target. Miller notes itching, hair loss, sores, and infections. VCA Animal Hospitals notes itching is the most common allergy sign in pets. Sneezing without itching or skin change fits allergy less well.
Is it seasonal or year-round?
The Merck Veterinary Manual describes seasonal feline nasal allergies as usually pollen-triggered but less common than in people. Signs appear when pollen is in the air. An indoor cat with winter sneezing likely faces another trigger. The Merck Veterinary Manual lists molds, dander, bedding, or feeds as nonseasonal causes.
The Merck Veterinary Manual says feline cases can be seasonal or year-round in its guide to rhinitis and sinusitis in cats. Pollen drives the seasonal form, while indoor allergens drive winter signs. Dusty litter areas, damp rooms, and new bedding deserve a first check. Note when sneezing starts, stops, and worsens.
What else causes lasting sneezing?
The Merck Veterinary Manual Professional Version names two top causes of acute rhinitis: feline herpesvirus type-1/rhinotracheitis and calicivirus. Bacteria are often secondary. A chronic sneezer may carry lingering infection or flare-ups.
Do not assume allergy from sneezing alone. VCA Animal Hospitals states seasonal pet allergies only rarely cause sneezing, wheezing, or runny eyes. Itching is the most common sign. A sneeze-first pattern without itch needs infection, dust, or foreign material ruled out.
When should you call the vet?
Ongoing sneezing that does not settle needs a vet exam. Note timing, discharge, appetite, energy, and any new litter, bedding, or cleaners.
VCA Animal Hospitals lists these signs as reasons for rhinoscopy and workup in its overview of rhinoscopy workup. Call promptly if you see any of these: Bring videos and a simple log of sneeze fits and exposures. Early workup can separate allergy from infection and find blocks that need direct care.
