Why Your Cat Snores in Its Sleep
📝 Summary
Cat snoring can be normal — brachycephalic breeds have bent airways, and deep sleep or a twisted neck can bring it on — but obesity and sudden respiratory disease are causes worth acting on. Judge the reason by the cat's build, habits, and any other symptoms.
1 Common Causes
Facial structure: in short-nosed (brachycephalic) cats like Exotics and Persians, a short nasal bone and curved nasal cavity and upper airway make breathing noisy during sleep — this is normal, so don’t worry. Deep sleep: cats in deep sleep snore more easily and may twitch a paw or the whole body now and then; that is normal. Sleep posture: in an unfamiliar place a cat sleeps tense, but when fully relaxed it may twist its body and neck enough to obstruct airflow and snore — rare, since a cat that feels stuffy will shift position. Obesity: excess fat thickens the pharyngeal wall, narrows the throat and trachea, and enlarges the soft palate; awake, breathing is fine, but asleep the relaxed muscles and fat pressure (even tongue fall-back) cause noisy breathing. Obesity also invites fatty liver and diabetes, so slim an overweight cat to a healthy weight. Respiratory disease: a non-obese cat that suddenly snores may have rhinitis, pharyngitis, or tracheitis; with poor appetite, lethargy, sneezing, or nasal discharge, see a vet.
2 When to Worry
Snoring in a brachycephalic cat is usually normal. But if the habit appears suddenly along with other abnormal signs, take the cat to the clinic to check for respiratory illness.
