Plain-English summary
A female domestic shorthair cat developed muscle twitching, stiffness in her hind legs and tail, and was unable to urinate after receiving morphine through her spine for pain relief. The twitching stopped after she was treated with midazolam, and a urinary catheter was used until she could urinate normally again. Within 36 hours, she was back to her usual self. However, when she had a second surgery without morphine, her pain management required more attention.

Abstract
An adult female domestic shorthair cat developed myoclonus, muscle rigidity, and hypersensitivity of the hind limbs and tail with urinary retention following neuraxial administration of morphine. Myoclonic contractions resolved following treatment with midazolam and a urinary catheter was placed until normal micturition returned. The cat was clinically normal 36 hours after neuraxial morphine injection. The cat underwent a second surgery without neuraxial morphine and control of postoperative pain required more intervention. Key clinical message: Neuraxial morphine may cause myoclonus and urinary retention. The response to pharmacological treatment of myoclonus is varied, but a benzodiazepine drug may be effective.
