You will certainly need antibiotic treatment. Scratches are usually not as serious, but you should always clean them with an antibacterial scrub such as Betadine, and apply antibiotic ointment.

Very young kittens, less than one month old, tame very quickly and completely.

I refer to them as the brute force method and the starvation method.
