Cat Bites and Scratches: First Aid, Risks, and When to Seek Help

Cats may bite or scratch for many reasons. They might be scared, stressed, playful, or trying to protect themselves. While some injuries seem small, they should never be ignored. Even a tiny puncture or scratch can allow bacteria to enter the skin and lead to an infection.

Knowing what to do can help reduce the risk of complications and support faster healing. In this blog, you’ll learn about the issues a cat bite or scratch can cause, the immediate course of action, and when to seek medical help.

Let’s get started!

Why You Should Take a Cat Bite or Scratch Seriously?

Even if the wound looks minor, it can become infected within a short time. Cat teeth are sharp and can create deep puncture wounds that trap bacteria beneath the skin. Scratches can also introduce harmful germs, especially if they break the skin.

A cat bite or scratch may lead to:

• Pasteurella infection: 70 to 90% of cats have the bacteria Pasteurella multocid in their mouth. The bacteria can cause pain, redness, swelling, and infection within 12 to 24 hours. It can also lead to an infection called Cellulitis.
• Cat Scratch Disease: Also known as cat scratch fever, it is caused by the bacterium Bartonella henselae. The condition may result in swollen lymph nodes, fever, tiredness, and muscle aches.
• Tetanus: If your tetanus vaccination is not up to date, a bite or scratch may increase your risk of infection. Caused by a bacterium called Clostridium tetani, it can cause severe muscle stiffness and painful spasms.
• Rabies: A bite from an unvaccinated or unknown cat should always be assessed by a doctor, as rabies is very rare but can be fatal.

What Immediate Action Can You Take?

Taking the right steps as soon as possible can lower the chance of infection and help the wound heal properly.

• Find out the cat's vaccination status: If the cat is not your own or its vaccination history is unknown, seek medical advice immediately.
• Wash the wound immediately: Rinse the area under running water and gently clean it with soap for several minutes.
• Allow minor bite wounds to bleed slightly: A small amount of bleeding on its own may help flush out bacteria. Do not squeeze the wound aggressively.
• Apply an antiseptic: After cleaning, use an antiseptic solution to reduce the risk of infection.
• Cover the wound: Place a clean, sterile bandage over the injury to protect it from dirt and bacteria.
• Watch for signs of infection: Monitor the wound for the next 24 hours. Redness, swelling, warmth, pus, increasing pain, or fever should not be ignored.

When You Need to Visit the Doctor?

It is advised to visit the doctor within 8 hours of the cat bite or scratch, especially if the bite punchers the skin.

The doctor will examine the wound and assess the risk of infection. They will clean the wound thoroughly and may remove damaged tissue if needed. Depending on the depth and location of the wound, they may prescribe antibiotics to prevent or treat a bacterial infection.

Your doctor will also check whether you need a tetanus booster. If the cat's rabies vaccination status is unknown or there is a risk of rabies exposure, they may recommend rabies post-exposure treatment. In some cases, the wound may need follow-up visits to ensure it is healing properly.

Seek urgent medical care if the bleeding does not stop, the wound is deep, you have difficulty moving the affected area, or you notice signs of a serious infection such as spreading redness, severe swelling, or fever. Furthermore, older adults, diabetics or immune compromised people should seek immediate medical attention.

The Bottom Line

A cat bite or scratch may look harmless, but it should never be taken lightly. Cleaning the wound straight away and getting medical advice can help prevent serious infections and other complications. Acting quickly is the best way to protect your health and ensure the injury heals safely.
