Cat Bite Treatment Guidelines

Initial Wound Management

Immediately wash and flush all bite wounds thoroughly with soap and water for approximately 15 minutes to reduce infection risk and potential rabies transmission, as recommended by the Centers for Disease Control and Prevention 1, 2
Consider using a virucidal agent such as povidone-iodine solution for irrigation, as suggested by the Centers for Disease Control and Prevention 1
Carefully examine the wound for tendon, bone, or joint involvement, which may be indicated by pain disproportionate to the injury, according to Praxis Medical Insights 3
The decision to suture large wounds should take into account cosmetic factors and the potential for bacterial infection, as recommended by the Centers for Disease Control and Prevention and Praxis Medical Insights 1, 2

For penicillin-allergic patients, alternative options include doxycycline or a fluoroquinolone plus an agent active against anaerobes, as suggested by Praxis Medical Insights 2
Avoid first-generation cephalosporins, penicillinase-resistant penicillins, macrolides, and clindamycin alone as they have poor activity against Pasteurella multocida, according to Praxis Medical Insights 2
For severe infections requiring intravenous therapy, options include β-lactam/β-lactamase combinations, piperacillin-tazobactam, second-generation cephalosporins, or carbapenems, as recommended by Praxis Medical Insights 2

Other common pathogens include staphylococci, streptococci, and anaerobes such as Bacteroides species, fusobacteria, Porphyromonas species, and peptostreptococci, according to Praxis Medical Insights 2

Assess the need for rabies prophylaxis based on the vaccination status of the cat, circumstances of the bite, and whether the animal can be observed for 10 days, as recommended by the Centers for Disease Control and Prevention 1
If rabies prophylaxis is indicated, administer both rabies immune globulin and rabies vaccine, with the first dose of vaccine given as soon as possible after exposure, according to the Centers for Disease Control and Prevention 1
Administer tetanus prophylaxis as indicated based on the patient's immunization status, as recommended by Praxis Medical Insights 2, 3

Hand wounds (particularly over joints, tendons, or bones) have higher risk of complications and should always receive antibiotic prophylaxis, according to Praxis Medical Insights 2
Immunocompromised patients, including those with asplenia or liver disease, are at higher risk for severe infections, including Capnocytophaga canimorsus bacteremia, as suggested by Praxis Medical Insights 3
Potential complications to monitor include septic arthritis, osteomyelitis, subcutaneous abscess formation, tendonitis, and bacteremia, according to Praxis Medical Insights 2, 3
