The Short Answer
A cat scratch that breaks skin can be a rabies exposure, even without bleeding. You cannot reliably judge saliva contamination by looking at the scratch. Wash with soap and running water for about 15 minutes and seek prompt medical or public-health advice. A pet’s normal appearance or vaccination record does not by itself rule out exposure.
Rabies can spread when infectious saliva or nervous tissue reaches broken skin or the eyes, nose, or mouth. A scratch can introduce saliva, and its appearance cannot establish whether contamination occurred. Calling a scratch “clean” does not establish that it was free of infectious material. See CDC: transmission routes and exposure assessment.
How Bites and Scratches Can Expose Someone
Bites commonly introduce saliva into tissue. Scratches can also break the skin and introduce infectious material. Wound depth varies; lack of bleeding does not prove that skin is intact.
WHO classifies minor non-bleeding scratches or abrasions from a suspect rabid animal as category II exposure, requiring wound washing and immediate vaccination. Scratches that pass through the skin are category III; treatment also includes rabies immunoglobulin or monoclonal antibodies when indicated. Local protocols and prior vaccination affect the regimen; a professional should make that decision. See WHO: category II and III exposures.
When to Seek Assessment
Seek prompt medical or public-health advice after a scratch that breaks skin or when you are unsure whether it did. This includes scratches from familiar pets. Do not wait to see saliva, bleeding, or illness in the animal.
A clinician or public-health professional should assess the animal, type of contact, wound depth and site, where the encounter happened and local rabies activity, and options for observation or testing.
Contact confined to intact skin is not a rabies exposure. This does not include an abrasion without bleeding or saliva entering the eyes, nose, or mouth. Ask a professional if the contact is uncertain.
What to Do After a Cat Scratch
- Wash and flush thoroughly with soap and running water for about 15 minutes when possible. This is an important early step. See WHO: prompt wound washing.
- Apply antiseptic such as povidone-iodine.
- Identify the cat and its vaccination status if possible.
- Check your tetanus booster history. A healthcare professional should assess whether you need a tetanus vaccine based on the wound and your vaccination history. See CDC tetanus wound-care guidance.
- Watch for signs of bacterial infection over the next 1-3 days: redness, swelling, warmth, pus, fever, red streaking from the wound, or pain disproportionate to the wound.
- Seek prompt professional advice for a skin-breaking scratch or uncertain contact, including from a familiar pet.

Cat Scratch Fever Is Not Rabies
This is the most common confusion in this topic. Cat scratch fever — also called cat scratch disease (CSD) — is a bacterial infection caused by Bartonella henselae, not rabies. They are completely different illnesses with different treatments and different prognoses.
Symptoms and Care
Cat scratch disease can cause a bump at the injury, fever and tender swollen lymph nodes. Some people develop more serious illness. A clinician should evaluate symptoms and decide whether treatment is needed; these symptoms do not establish whether rabies exposure occurred. See CDC: cat scratch disease transmission, symptoms and care.
Scratch From an Indoor Cat
Indoor living and vaccination help reduce risk but do not establish whether a particular contact was an exposure. Report any possible wildlife contact, including bats indoors, to your clinician and veterinarian. Seek prompt advice after a skin-breaking scratch.
Seek prompt professional assessment; do not wait for observation to finish. Public-health authorities can arrange a full 10-day observation for an eligible dog, cat, or ferret and use the result to guide PEP. See CDC veterinary guidance: supervised observation. Do not start, delay, or stop PEP on your own.
Scratch From a Stray or Feral Cat
For an unfamiliar animal, vaccination history and observation options may be uncertain. Tell the assessing professional what is known; do not assume infection or vaccination status.
Seek prompt professional assessment for a skin-breaking scratch from a stray or feral cat, including a minor abrasion without bleeding. Ask animal control about locating the cat; do not attempt capture yourself.
If the cat can be safely captured for observation or testing, animal control will coordinate. A cat that remains healthy throughout a properly supervised 10-day observation is considered not to have been infectious at the time of the scratch. Seek prompt professional assessment; do not wait for observation to finish. Public-health authorities can arrange a full 10-day observation for an eligible dog, cat, or ferret and use the result to guide PEP. See CDC veterinary guidance: supervised observation. Do not start, delay, or stop PEP on your own.
Next Steps
Wash a scratch promptly. If skin is broken or contact is uncertain, seek medical or public-health assessment. Normal appearance, vaccination, no visible saliva, and no bleeding do not by themselves rule out exposure. Seek prompt professional assessment; do not wait for observation to finish. Public-health authorities can arrange a full 10-day observation for an eligible dog, cat, or ferret and use the result to guide PEP. See CDC veterinary guidance: supervised observation. Do not start, delay, or stop PEP on your own.
