Typically viral, but occasionally bacterial, this condition can arise from <jats:italic>Bartonella henselae<\/jats:italic>, a rare yet potentially serious pathogen that can lead to cardiac inflammation and subsequent heart failure.

We present a mid-30s man, immunocompetent, who presented to the emergency department with acute heart failure due to <jats:italic>B. henselae<\/jats:italic>-associated perimyocarditis. Despite not recalling any scratches or bites from cats, the patient had been living with cats, which likely exposed him.
