Abstract:

A 6-month-old kitten developed a hoarse, raspy breathing pattern the day after being spayed under a general anaesthetic but without endotracheal intubation. This progressed to dyspnoea and open mouth panting the following day. On presentation, the cat exhibited a harsh, raspy sound on inhalation which could be localised to the larynx on auscultation. Thoracic and abdominal radiographs showed hyperinflation of the lungs and aerophagia. The kitten was treated for presumptive laryngitis and responded rapidly to a high dose of dexamethasone and oxygen therapy. Mild residual clinical signs gradually resolved over 7 days.

This case highlights laryngeal inflammation as an important diagnostic consideration in dyspnoeic cats, especially when airway stertor can be localised to the larynx. A recent history of anaesthesia without intubation suggested the possibility of reflux laryngitis as the cause of the laryngeal dysfunction.
