*Oesophagitis can occur secondary to persistent vomiting, secondary to reflux of gastric juice, secondary to hiatal hernia, and following ingestion of caustic substances.

*Oesophageal motility disorders include primary megaoesophagus, myasthenia gravis, dysautonomia, and polymyopathy. Of these potential causes, acute onset regurgitation in a young cat would be most commonly due to oesophagitis, oesophageal stricture, foreign body, anterior mediastinal lymphoma, primary megaoesophagus, and persistent right aortic arch. The recent onset of signs would suggest the latter two are less likely.
