Hi Ash
Welcome to the forum! I am the resident bengal nut here LOL - have mmmmmm forgot how many now LOL
Its really good that you are doing your research on the breed, too many people just decide to get one because of the look. In terms of reference material I would point you to the Bengal Cat Forum (if you type this into google you will get the link). You will meet lots of bengal lovers and owners here both breeders and pet lovers alike
There are lots of posts on behaviour, nutrition, general topics etc. Great source of information.
In terms of special requirements, I think the one thing that I would say to you is they do have high energy requirements and want lots of social contact. You need to ensure you can create the right environment for them indoors (would never recommend letting a bengal cat out to roam). If you are out all day working (which most of us are) I would consider a pair of kittens rather than one. A bored bengal can be a destructive bengal, not always the case but it can happen!
Bengals can get along with other cats just fine. Its really a personality thing as much as anything I think (oh and of course whether or not your resident cats can keep up with them LOL).
I am happy to answer any specific questions you have on bengals. Just drop me a PM
