A 2-year-old 5-kg spayed female Turkish Angora cat was presented for evaluation because of recurrent episodic weakness and tachypnea. The cat had had recurrent tachycardia (> 180 beats/min; reference range,1 107 to 129 beats/min [home auscultation]) for several hours and had been tachypneic (> 70 breaths/min; reference range,2 36 to 39 breaths/min [awake adult respiratory rate]) during each episode. The cat had a 6-month history of episodic weakness, lethargy, dilated pupils, and pale foot pads, with clinical signs confirmed at least 4 times over 4 months.

On physical examination, the cat’s systolic arterial pressure was
