In humans, P. multocida is the most common cause of wound infections after dog or cat bites. The infection usually shows as soft tissue inflammation within 24 hours. High leukocyte and neutrophil counts are typically observed, leading to an inflammatory reaction at the infection site (generally a diffuse, localized cellulitis). [8]
Symptoms typically begin within 3–14 days following infection. [2] Cat-scratch disease is caused by the bacterium Bartonella henselae which is believed to be spread by the cat's saliva. [2] Young cats pose a greater risk than older cats. [3] Occasionally dog scratches or bites may be involved. [3] Diagnosis is generally based on symptoms. [3]

Cat bites are bites inflicted upon humans, other cats, and other animals by the domestic cat (Felis catus). [1] [2] Data from the United States show that cat bites represent between 5–15% of all animal bites inflicted to humans, [3] [4] but it has been argued that this figure could be the consequence of under-reporting as bites made by cats are considered by some to be unimportant.
