Unfortunately, parasites such as fleas can infest small animals such as kittens. Little kittens are more susceptible to flea infestation because of the fact that their body has not yet fully developed and their resistance to parasites is weaker than that of an older cat.

Flea infestation among kittens becomes prevalent, especially if she is exposed to different animals that are carriers of these parasites. Fleas can lay hundreds of eggs at one time; hence they can reproduce faster and can get transmitted faster too.
It is highly recommended that if you have kittens at home, do not let them get in contact with other animals as much as possible. If it cannot be avoided, make sure that your kitten’s sleeping space is clean and that her beddings are well-maintained to prevent fleas from breeding there.
You must also check the mother cat and make sure she is not infested with fleas herself, as she may transmit those to her kittens very easily.
