Emergency treatment methods for scratches by cats without bleeding:

1. The scratched person should be rinsed and soaked repeatedly with saline, hydrogen peroxide and iodophor water in a timely manner. The wound surface of the injured area can be effectively discharged from the necrotic material and the bacteria can be effectively killed.

2. After soaking and disinfecting the wound, apply Baiduobang ointment or chlortetracycline eye ointment evenly to the scratched wound to protect the wound from inflammation and sterilization.

3. Use a small patch or gauze to properly bandage the wound to protect it from secondary contamination by sewage or dust.

Whether you need to be vaccinated if you are scratched by a cat and there is no bleeding depends on the situation. Situations where you need to be vaccinated if you are scratched by a cat:

1. As long as there is bleeding after being scratched by a cat or dog, it is considered a level three exposure, and everyone should actively go to the epidemic prevention station to get rabies vaccination.

2. If you are scratched by a stray cat in the wild or an unfamiliar cat, you must get a rabies vaccine in time. After being scratched, in addition to vaccination, you also need to rinse the wound with soap and water in time, rinse repeatedly for more than 20 minutes, and then go to the epidemic prevention department to get rabies vaccine in time.

3. If the scratch wound is particularly large and the amount of bleeding is large, serum immunoglobulin needs to be injected at the same time to achieve a more rapid effect of blocking rabies.

If you are scratched by a cat, you should not get vaccinated:

1. If the skin is scratched by a cat and there is no damage or obvious redness, vaccination is generally not required.

2. When in contact with animals, if there is no obvious skin damage or bleeding, injections are not required.
