Is Cat Snoring a Sign of Illness? Checking the Nose and Airways
🚨 Check first
If your cat breathes with an open mouth (panting) or flares their nostrils and heaves their belly to breathe while awake—not just while asleep—this is breathing distress, not simple snoring. See a vet immediately.
📌 The answer in 3 seconds
- Soft, quiet breathing sounds or cute little chirps and twitches during deep sleep are normal physiological phenomena and nothing to worry about. Flat-faced (brachycephalic) breeds such as Persians, Exotic Shorthairs, and Himalayans are also structurally prone to snoring.
- However, if a cat that never snored before suddenly starts snoring loudly like a human or making congested snuffling sounds—especially alongside nasal discharge, eye discharge, or sneezing—suspect rhinitis or sinusitis from an upper respiratory infection, nasal polyps or tumors, or airway narrowing from obesity.
- Take a smartphone video capturing the snoring sound and sleeping posture, and have your vet check the nasal passages and airways if it continues.
📊 Flowchart
- Step 1Use your smartphone to record a 30-second video capturing the volume, rhythm, and sleeping posture while your cat is snoring.
- Step 2Check whether your cat also makes snuffling nasal sounds while awake, sneezes, has nasal discharge (especially pus or blood-tinged discharge coming from only one nostril), or seems to have trouble swallowing food.
- Step 3Use a humidifier to keep room humidity at 50–60% to prevent dry airways, work on gradual weight management if your cat is overweight, and bring your video to the vet for a consultation.
⭕ Step-by-step fix
Step 1 · What you can do at home right now
Use your smartphone to record a 30-second video capturing the volume, rhythm, and sleeping posture while your cat is snoring.
Step 2
Check whether your cat also makes snuffling nasal sounds while awake, sneezes, has nasal discharge (especially pus or blood-tinged discharge coming from only one nostril), or seems to have trouble swallowing food.
Step 3
Use a humidifier to keep room humidity at 50–60% to prevent dry airways, work on gradual weight management if your cat is overweight, and bring your video to the vet for a consultation.
❌ Never do this
- Ignoring sudden loud snoring or nasal congestion sounds for months under the assumption that your cat is just sleeping soundly (this can delay the detection of nasal tumors or polyps in middle-aged and senior cats).
- Putting human nasal drops or sprays into a congested cat's nose.
