No, Bengal cats are not dangerous to people. They might be dangerous to mice, though! If they are allowed to hunt outside, which is unlikely. Or birds and so on but people, no, provided they are socialised like any other well bred and raised purebred cat.
As mentioned Bengal cats are purebred. They’ve been created through artificial selection by a hobby breeder. The task of a cat breeder is to create great cat companions. They achieve this by ensuring that their cats (1) look great and (2) behave great.
They achieve the former through careful selective breeding to ensure that their appearance matches as near as possible the guidelines of the breed standard to which the cat is registered. They achieve the latter both through selective breeding and careful socialisation during the early weeks of life.
Socialisation means the cat has learned to be at ease living with humans and other animals. They have been exposed to humans and I would hope other animals. This makes them domestic animals who are not fearful of humans. In being non-fearful they are friendly and in turn do not pose a danger to people.
If they are unsocialised to humans, like feral cats, they are fearful of them. This leads to a aggressive defensive behaviour in the company of people which can lead to bites and swipes. That’s why feral cats can be dangerous to the extent that they can harm people if they force themselves onto a feral cat such as picking one up when they want to run.
Bengal cats are likely to be less dangerous than the average domestic, community or feral cat because they have been bred. You know that they have been ‘created’ to live in harmony with people in the home.
There is one minor exception or qualification which is that most Bengal cats are fifth filial e.g. five generations from the wild. If you live with a first filial Bengal cat which is half wild cat (Asiatic leopard cat) and half domestic cat, the F1 Bengal cat is likely to be a bit of a handful.
They are active and intelligent with a healthy amount of wild blood. The Asiatic leopard cat is known to be particularly independent-minded and difficult to live with unless you use enclosures. Under certain circumstances an F1 Bengal cat might be dangerous if provoked through a lack of understanding of the requirements of such a breed and filial.
So I can’t say that in all cases and under all circumstances Bengal cats are always non-dangerous. They might be but very few people live with F1 or F2 Bengal cats. Nearly all Bengals are five generations from the wild and almost identical to standard moggy domestic cats in character.
Conclusion: Bengal cats are not dangerous.
