Our local bengal actually attacked me when I tried to defend my cats against him, he turned on me and ran up my leg and hung off my shoulder and I spent a delightful afternoon at the local walk in centre getting cleaned up, tetanus and antibiotic. I have a splendid set of scars and my cat was nearly killed - personally I wouldn't free range bunnies in the garden at all if I knew there were bengals in the neighbourhood, they will easily jump a 6ft fence and in some ways that's worse than open fences because you can't see them coming!
When I looked into it before, I also learnt that unlike most cats, many bengals actually like water so water pistols don't always work on them - I was told they hate noise though so I was advised to fill a plastic tub with stones and throw it on the floor instead.
