An adult female Canadian lynx (Lynx canadensis) was presented with a 3-wk history of anorexia and lethargy. Initial examination and diagnostics did not provide a diagnosis. The lynx continued to demonstrate vague clinical signs, including anorexia and an abnormal gait. During follow-up immobilizations 2 wk later, a barium gastrointestinal study revealed a pyloric obstruction. Abdominal exploratory surgery was elected, and a gastrotomy and an enterotomy of the proximal duodenum were performed to remove the pyloric obstruction. The obstruction was determined to be a trichobezoar. Fleas, a likely cause of hair ingestion through grooming, were noted during surgical preparation. The lynx made a full recovery from surgery. Reoccurrence of the trichobezoar was prevented after surgery with the use of monthly flea control and three times a week hairball laxative.
