How to clean kittens
If your kitten isn't too dirty, wipe her down with a wet cloth.
Kittens habitually clean themselves with their tongues, but there are some spots that they have trouble reaching-namely, the head, the back, and the behind. Mother cats usually help kittens clean these spots.
Your job, as surrogate mother cat, is to clean your kitten regularly to ensure that she is healthy and hygienic. Wiping with a wet cloth also uses less water than a full bath.
