Sneezing does not prove that a rat has an infection. Irritants and disease can cause similar signs, so the cause cannot be diagnosed from a sneeze alone.

When to seek help

Contact a vet if your rat is sneezing repeatedly, wheezing, breathing unusually, becoming less active or eating less. Open-mouth breathing or obvious difficulty breathing needs urgent veterinary attention.

Check the environment

Dusty litter, aromatic cedar bedding and ammonia from accumulated urine can irritate a rodent’s airways. Improve cleanliness and reduce these irritants while arranging appropriate care.

Why this page changed

The inherited article recommended supplements, baths and other home remedies as treatments. Those instructions and its unverified veterinary-practice identity have been removed. Diagnosis and any prescribed treatment belong with a vet experienced in rats.
