Careful examination may reveal an inoculation papule in the majority of patients. Given the tendency to hold cats against one's chest, the lesion is found most often on the head or upper extremities. Include the scalp, finger web spaces, eyelids, and conjunctiva in a thorough inspection. Multiple sites may be infected.
