The two Bengals I have know have given their human companions some stress. Unlike other breeds, they are fairly close in generations from some very wild genes. If there is another cat in the household, it needs to be the Alpha cat or strong enough to defend itself as the Bengal will challenge it's position.

One young female I know took a dislike to her owner's girlfriend and bit her at every opportunity. At eight months old, she was strong enough to push a sliding glass door open (left open about one inch for ventalation) and was found walking around on the balcony rail 12 stories up.

The Story of Ti and Miley is well documented here. Ti, a Bengal, became more agressive as Miley became more frightened of him and he put Milley in the hospital with injuries.

On the other side of the coin, they are quite beautiful and, in a single-pet household, a Bengal should do quite well.
