Cat bites are a distant second to dog bites in frequency among animal bites — but they are uniquely dangerous because of the specific bacteria cat teeth introduce deep into the tissue. The narrow, sharp puncture wounds cat teeth produce can deliver bacteria deep into joints, tendon sheaths, and bone — areas where infection is particularly difficult to clear once established. Cat bites can be physically and emotionally challenging for any patient, and especially for children. Beyond the bacterial concern, deeper cat bites can damage important nerves, tendons, blood vessels, and occasionally bones of the hand. Effective cat bite management requires both prompt antibiotic decision-making and an understanding of the deeper hand anatomy that may be involved. At Los Angeles Plastic Surgery in Beverly Hills, Dr. John Anastasatos manages hand and upper extremity infections with the depth of training this complex condition specifically rewards.

Dr. Anastasatos manages cat bite injuries with the most directly relevant academic credential possible: he completed a fellowship in Hand and Upper Extremity Surgery and Microsurgery at the University of Alabama at Birmingham — formal subspecialty training in hand surgery that few cosmetic plastic surgeons possess. He has presented academic work at UAB Grand Rounds on “Infections of the Hand” — directly relevant to the bacterial management cat bites specifically require. With over two decades of facial and hand surgical expertise in Beverly Hills since 2007, he is board certified by the American Board of Plastic Surgery, a Fellow of the American College of Surgeons (FACS), a member of the American Society of Plastic Surgeons (ASPS) and American Society for Aesthetic Plastic Surgery (ASAPS), and named by The Luxe Insider as one of the Top 10 Plastic Surgeons in the World.

Initial Cat Bite Evaluation

Cat bite injuries can range from simple scratches to deep, complex wounds — and the initial evaluation should maintain a high index of suspicion for deeper injury:

• Examination for deeper structural injury to nerves, tendons, blood vessels, and bones of the hand
• X-rays to rule out bone fractures (rare with cat bites because their teeth and jaw strength are not particularly conducive to fracture, but should still be excluded)
• MRI or CT scan when infection or compartment syndrome is suspected in the deeper tissues and fascial layers of the hand, wrist, or forearm
• Tetanus immunization status check — booster recommended if not within the last 5 years
• Rabies prophylaxis evaluation — rabies immune globulin (RIG) recommended if the cat’s immunization history is unknown

Wound Management

Wound management depends on the depth and complexity of the injury:

• Simple scratches and puncture wounds — irrigated thoroughly in the emergency room, washed out, and allowed to heal by secondary intention. Wound management and pressure irrigation are the mainstay of treatment for animal bites.
• Deeper but uncomplicated wounds — copious irrigation, debridement of foreign debris and devitalized tissue, then surgical closure. Hand and limb elevation help reduce swelling.
• Complex wounds, face/neck wounds, and pediatric wounds — treated in the operating room under general anesthesia, with copious irrigation using normal saline and antibiotic solution, thorough wound debridement, and layered closure

Antibiotic Strategy for Cat Bites

Dr. Anastasatos is a proponent of early antibiotic use for cat bites — a position grounded in the specific bacteriology of these injuries. The most common organism responsible for cat bite infection is Pasteurella multocida, which is not susceptible to cephalexin or clindamycin — common antibiotics that fail in this setting and lead to progressive infection.

The recommended antibiotic strategy:

• First-line oral therapy: Amoxicillin/clavulanate (Amoxil) — covers Pasteurella multocida effectively
• Emergency room or operating room IV therapy: Ampicillin/sulbactam (Unasyn) — strong intravenous coverage
• Penicillin allergy: Doxycycline or erythromycin — note that doxycycline should not be given to women who may be pregnant
• Additional or alternative coverage: Sulfamethoxazole/trimethoprim (Bactrim) — used alone or in combination
• Other options: Second- and third-generation cephalosporins or metronidazole

The early decision to use the right antibiotic matters meaningfully for outcomes — and is a key reason cat bites should be evaluated by a clinician with hand infection experience rather than assumed to be minor injuries.
