The causative organism was first thought to be ''Afipia felis'', but this was disproved by immunological studies demonstrating that cat scratch fever patients developed antibodies to two other organisms, ''Bartonella henselae'' and ''Bartonella clarridgeiae'', which are rod-shaped [[Gram negative]] bacteria.

Most cases are [[benign]] and self-limiting, but [[lymphadenopathy]] may persist for several months after other symptoms disappear. The prognosis is generally favorable. In temperate climates, most cases occur in fall and winter.  The disease usually resolves spontaneously, with or without treatment, in one month. In [[immunocompromise]]d patients more severe complications sometimes occur.
