Cat Scratch Disease or sometimes called cat scratch fever is an infection cause by a lick, scratch or bite from an infected animal, most often cats and kittens. This bacteria is transmitted through the feces (poop) of infected fleas.
Signs and symptoms can be mild to severe and often include redness at the scratch or bite site, swollen lymph nodes and low-grade fever. Most cases get better on their own. Children under the age of five years and individuals who are immunocompromised are more at risk of severe illness.
