Can a Cat Scratch Make You Sick? Understanding the Risks and Prevention

Cats are wonderful companions, but as adorable as their playful antics can be, even a small scratch from your feline friend has the potential to cause health issues. At Renfrew Animal Hospital, we believe in keeping both you and your pets healthy, so we’re breaking down what you need to know about cat scratches, the risks involved, and how to prevent problems.

What Makes a Cat Scratch Risky?

While most cat scratches are harmless, some can lead to infections or diseases. Here are the primary concerns associated with cat scratches:

  1. Cat Scratch Disease (CSD): Cat Scratch Disease, caused by the bacterium Bartonella henselae, is the most common illness linked to cat scratches. Cats often carry this bacterium without showing symptoms, usually after being exposed to fleas. If a cat scratches you, the bacteria can enter your skin and lead to symptoms such as:
    • Swollen, tender lymph nodes near the site of the scratch.
    • Fever, fatigue, and headaches.
    • In some cases, more severe complications in individuals with weakened immune systems.
  2. Bacterial Infections: Even if Bartonella henselae isn’t present, cat claws can introduce other bacteria into the skin, such as Staphylococcus or Streptococcus, which may cause redness, swelling, or even an abscess at the site of the scratch.
  3. Tetanus: Though rare, tetanus is a risk if the scratch is deep and the individual isn’t up to date on their tetanus vaccine.
  4. Other Zoonotic Diseases: Cats with outdoor access may pick up pathogens from their environment, potentially passing them to humans through scratches or bites.

Who Is at Greater Risk?

Certain individuals are more susceptible to complications from cat scratches, including:

  • Children: They may not understand how to handle cats gently, leading to more scratches and potential infections.
  • Older Adults: With age, immune systems weaken, increasing susceptibility to infections.
  • Immunocompromised Individuals: Those undergoing chemotherapy, organ transplant recipients, or individuals with conditions like HIV are at higher risk for severe infections.

Preventing Problems from Cat Scratches

At Renfrew Animal Hospital, we advocate for proactive measures to keep both you and your cat healthy. Here’s what you can do:

  1. Keep Your Cat’s Claws Trimmed: Regular nail trims reduce the likelihood of deep scratches. If you’re unsure how to trim your cat’s claws safely, our team can show you or handle it during your cat’s next visit.
  2. Control Fleas: Since fleas are the main source of Bartonella henselae, maintaining year-round flea prevention is essential. We offer safe and effective flea treatments to keep your cat’s environment pest-free.
  3. Encourage Gentle Play: Teach your cat to play with toys instead of using their claws on human hands or feet. Redirect their attention to a wand toy or laser pointer when they get too rough.
  4. Practice Proper Wound Care: If you do get scratched:
    • Wash the area immediately with soap and water.
    • Apply an antiseptic or antibiotic ointment.
    • Monitor for signs of infection, such as increased redness, warmth, swelling, or pus. If these occur, seek medical attention promptly.
  5. Vaccinate and Regular Vet Visits: Keep your cat’s vaccinations, such as rabies, up to date, and schedule regular wellness exams to ensure they’re healthy and free from conditions that could be transmitted to humans.
