Bitten by a cat, but the skin was not broken; swelling occurred.

Generally, if bitten by a cat without broken skin but with swelling, treatment should include washing with clean water, cold compresses, and medication. The specific approach is as follows:

1. Wash with clean water

After being bitten by a cat, immediately rinse the area around the wound with clean water and disinfect the wound. Antiseptics such as povidone-iodine or alcohol can be used. For minor cat bites, normal saline may suffice for rinsing without additional antiseptic solutions.

2. Apply cold compress

After a cat bite, apply an ice pack or ice wrapped in a cloth for 15–20 minutes at a time, 2–3 times daily. Cold compresses help relieve pain and reduce swelling.

4. Use medication

If pain and swelling are severe, certain medications may be used for treatment. For example, cephalosporin or penicillin antibiotics can help prevent further bacterial spread. However, these should only be taken as directed by a physician.

In addition, other methods such as acupuncture or massage may also be considered. After a cat bite, it's particularly important to watch for signs of infection. If swelling persists, pain worsens, or other abnormal symptoms develop, prompt medical attention is recommended for evaluation and treatment.
