Treatment for ringworm in kittens:
1. Kittens should be isolated from other cats, and their living environment should be thoroughly disinfected.
2. Shave the hair in the affected area to make it easier to apply medication. If it's just mild milk rash, simply clean the affected area daily and then apply a topical antifungal medication. If it's more severe, oral medication may be necessary. 
3. Pay attention to providing kittens with adequate nutrition, and appropriate sun exposure can also help with the recovery of milk rash.
4. Do not let the affected area of your cat bump or fall into other places. Try to prevent your cat from running, as this will affect its recovery.
5. After the kitten's affected area has healed, it still needs to go to the hospital for an examination to confirm that the fungus on the kitten's skin has completely disappeared. Medication can only be stopped after consulting a veterinarian, otherwise the condition may recur.
