Reasons Why Cats Snort

Why do cats snore when they sleep? Most cases are harmless, but sometimes the sound is a red flag. Here’s a quick split between “normal” and “see the vet”.

HARMLESS REASONS

  1. Weird sleeping position
    Head jammed into the sofa gap, neck twisted, or sleeping on their back can make the soft palate droop and vibrate—change the angle and the snore stops.
  2. Breed anatomy
    Flat-faced (brachycephalic) breeds—Persians, Himalayans, Exotic Shorthairs—have short, narrow nasal passages and an elongated soft palate, so air turbulence is almost built-in.
  3. Deep-sleep relaxation
    Cats clock 12–20 h of sleep a day; during REM every muscle loosens, the soft palate flutters more and you hear that gentle rattle.

WHEN TO WORRY

  1. Overweight
    Fat deposits around the neck compress the airway. Obese cats are 2–3× more likely to snore and can develop short apnoeic pauses.
  2. Upper-respiratory disease
    Chronic rhinitis, sinusitis, feline asthma or bacterial infections congest the nasal cavity; expect continuous snoring plus sneezing, nasal discharge or wheezing.
  3. Obstructive foreign body / mass
    Grass seeds, polyps or tumours create one-sided snoring, pawing at the face or rapid breathing.
  4. Senior changes
    Age-related loss of laryngeal muscle tone lets the airway collapse. Progressive louder snores deserve imaging (X-ray or CT).

HOME CHECKLIST

  • Sound: soft & intermittent = usually positional; high-pitched or constant → vet.
  • Timing: only in deep sleep = OK; snores while awake = investigate.
  • Extras: sneezing, nasal drip, open-mouth breathing, weight loss or lethargy → book an exam.

PREVENTION & FIXES

  • Keep body-condition score ≤ 5/9; limit high-carb treats.
  • Vaccinate and regular health checks to cut respiratory infections.
  • Dust-free, 40–60 % humidity, no cigarette smoke.
  • For severe brachycephalic cases your vet may discuss soft-palate resection or widening the nares.

Bottom line: brief, posture-related purr-snores are fine; persistent, worsening or symptom-accompanied snoring needs a vet work-up for obesity, infection or obstruction.
