Scratches from a Cat
- Bite or claw wound from a pet, farm or wild animal
- Bite from a human child or adult
Risk of Bites
- Animal or human bites usually need to be seen because all of them are contaminated with saliva and prone to wound infection.
Types of Wounds
- Bruising: There is no break in the skin. No risk of infection.
- Scrape (abrasion) or Scratch: A superficial wound that doesn’t go all the way through the skin. Low risk of infection. Preventive antibiotics are not indicated.
- Laceration (cut): A wound that goes through the skin (dermis) to the fat or muscle tissue. Intermediate risk of infection. Most need to be seen. Wound cleansing and irrigation can help prevent infection by washing out the bacteria from the wound. Preventive antibiotics may be required.
- Puncture Wound: Intermediate risk of infection. Puncture wounds from cat bites are especially prone to getting infected; many physicians will prescribe preventive antibiotics for cat bites.
Types of Bites
- Bites from Rabies-Prone Wild Animals: Rabies is a fatal disease. Bites or scratches from a bat, skunk, raccoon, fox, coyote, or large wild animal are especially dangerous. These animals can transmit rabies even if they have no symptoms. In the U.S., 90% of cases of rabies in humans is attributed to bats. Bats have transmitted rabies without a detectable bite mark.
- Small Wild Animal Bites: Rodents such as mice, rats, moles, gophers, chipmunks, prairie dogs and rabbits fortunately are considered free of rabies. Squirrels rarely carry rabies, but have not transmitted it to humans.
- Large Pet Animal Bites: Most bites from pets are from dogs or cats. Bites from domestic animals such as horses can be handled using these guidelines. Dogs and cats are free of rabies in most metro areas. Stray animals are always at risk for rabies until proven otherwise. Cats and dogs that are never allowed to roam freely outdoors are considered free of rabies. The main risk in pet bites is serious wound infection, not rabies. Cat bites become infected more often than dog bites. Claw wounds from cats are treated the same as bite wounds, since the claws may be contaminated with saliva.
- Small Indoor Pet Animal Bites: Small indoor pets (gerbils, hamsters, guinea pigs, white mice, etc.) are at no risk for rabies. Tiny puncture wounds from these small animals also don't need to be seen. They carry a small risk for wound infections.
- Human Bites: Most human bites occur during fights, especially in teenagers. Sometimes a fist is cut when it strikes a tooth. Human bites are more likely to become infected than animal bites. Bites on the hands are at increased risk of complications. Many toddler bites are safe because they don't break the skin.
Dogs and Cats and the Risk of Rabies
- Indoor versus Outdoor Pets: Dogs and cats that are never allowed to roam freely outdoors are considered free of rabies. Outdoor pets who are  stray, sick or unvaccinated AND  living in communities where rabies occurs in pets are considered at risk for Rabies in the U.S. and Canada.
- Metropolitan versus Rural Location: Dogs and cats in most metropolitan areas in the U.S. and Canada are free of rabies (Exception: towns along the border with Mexico.) Dogs and cats in rural areas have a higher risk of rabies.
- Provoked versus Unprovoked Bite: An unprovoked attack by a domestic animal increases the likelihood that an animal is rabid. Note that bites inflicted while a person is attempting to feed or handle a healthy animal are considered provoked.
- Developing Countries versus U.S. and Canada: Dogs and cats in developing countries have a higher risk of rabies; rabies postexposure prophylaxis is indicated if a bite occurs in a developing country. International travelers need to remain alert.
- Nurses and physicians must check with the local Public Health Department about the risk for rabies in their community.

HOME CARE ADVICE FOR ANIMAL OR HUMAN BITE
And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
- Wash all wounds immediately with soap and water for 5 minutes.
- Also, flush vigorously under running water for a few minutes (Reason: can prevent many wound infections).
- Scrub the wound enough to make it re-bleed a little. (Reason: to help with cleaning out the wound).
- Bleeding: For any bleeding, apply continuous pressure for 10 minutes.
- Antibiotic Ointment: For small cuts, apply an antibiotic ointment (e.g., Polysporin, Bacitracin) to the bite 3 times a day for three days. (No prescription needed.)
- Pain Medicine: Give acetaminophen (e.g., Tylenol) or ibuprofen for pain relief.
- Bruises: Apply a cold pack or ice bag wrapped in a wet washcloth once for 20 minutes. (Reason: reduce bleeding, pain and swelling)
- Expected Course: Most scratches, scrapes and other minor bites heal up fine in 5 to 7 days.
- Call Your Doctor If:
- Wound begins to look infected (pus, redness, red streaks)
- Fever occurs
- Your child becomes worse
