Cat Snoring: Is It Normal, Causes & When to See a Vet 2026

Cat snoring is the sound produced when soft tissues in the upper airway (throat, soft palate, or nasal passages) vibrate during breathing. Some cat snoring is perfectly normal — especially in brachycephalic breeds and older cats — but snoring that starts suddenly, gets louder, or is combined with other breathing changes can indicate a health issue.

This guide is for informational purposes. Consult your veterinarian if your cat’s snoring is new or has changed.

Is Cat Snoring Normal?

Yes, many cats snore regularly without any underlying health problem. Cat snoring during deep sleep is quite common, particularly in:

• Brachycephalic breeds (Persians, Himalayans, Exotic Shorthairs, Scottish Folds)
• Overweight cats — extra tissue around the throat can narrow the airway
• Older cats — airway tissues become less toned with age
• Cats sleeping in unusual positions that restrict airflow

A cat that has snored the same way for years without other symptoms is almost certainly fine. It’s new snoring, or changes in snoring character, that raise concern.

Common Causes of Cat Snoring

Flat-Faced Breeds and Snoring

Brachycephalic (flat-faced) cat breeds are anatomically prone to snoring due to their compressed facial structure. The most affected breeds include:

• Persian — the quintessential snoring cat breed
• Himalayan — Persian-derived; same anatomy
• Exotic Shorthair — Persian in a short coat
• Scottish Fold — rounded head contributes to airway compression
• British Shorthair — rounder face than most breeds

These breeds have narrowed nostrils (stenotic nares), elongated soft palates, and sometimes narrow windpipes. While mild snoring is normal and expected, significant breathing difficulties can be surgically corrected in some cases to improve quality of life.

If you have a brachycephalic cat, avoid exposing them to heat and humidity, as their compromised airways make temperature regulation more difficult. Keep them at a healthy weight and avoid stressful situations that increase breathing demand.

Concerning Signs to Watch For

Contact your vet if your cat’s snoring is accompanied by:

• Nasal discharge (one or both nostrils) — especially yellow, green, or bloody
• Open-mouth breathing when not stressed or post-play
• Labored breathing at rest
• Decreased appetite or difficulty eating
• Facial swelling or asymmetry
• Snoring that started suddenly in a cat that never snored before
• Snoring that is rapidly getting worse

Managing Cat Snoring at Home

For cats with benign snoring:

• Maintain a healthy weight — even moderate weight loss can significantly reduce snoring in overweight cats
• Keep the sleeping environment clean — dust, smoke, and strong scents can irritate airways
• Elevate the sleeping position — some cats snore less with a slightly elevated head; orthopedic or contoured pet beds can help
• Monitor for changes — baseline what’s “normal” for your cat; note any changes in volume, frequency, or character of snoring
• Annual vet check-ups — particularly important for brachycephalic breeds
