I'm in agreement with the other posters. 10-12 weeks minimum for all kittens, regardless of breed.
Kittens must be fully transitioned from mother's milk to solid foods and of equal importance is development of social skills learned from mom and siblings.
IMO, a major cause of personality issues in cats, is removing them from their mom and littermates too early. It's very detrimental to kittens and often the problems don't present themselves until the cat has become an adult.
Typical problems are: Biting, scratching, attacking, fearful behavior, only bonds to one person hates everyone else, etc.
As long as your bengal breeder has taken the time to interact with your new kitten on a regular basis, you will be blessed with a sweet well rounded kitten that has had the appropriate amount of time to adjust to this new world and will easily and confidently be able to transition to life in your home.
