It's my understanding that Bengals sold as pets by breeders are at least a couple of generations removed from the wild. They did cross the Asian wild cat with domestic cats, but the offspring of such crosses are crossed again with each other to breed true over several more generations. So, specimens of the Bengal domestic breed retain *some* wild traits in addition to looking wild (I've read that Bengals are *very* active), but are much tamer than a true wild cat.
As for cats liking to drink running water, I've had a couple of them who liked to drink from the bathroom sink faucet.
There are now several kinds of cat drinking fountains sold, in catalogues and pet stores, which have a reservoir and a pump to provide a stream of running water. They also have filters, etc., to keep the water clean and aerated.
The two cats I have now seem content to drink out of either regular bowls or long-term drinkers with plastic jugs that refill the bowls by gravity alone.
I have a cat which is supposedly part desert lynx. He's certainly different - wilder - than any other cat I've had. We had to board him for a week and they had to sedate him... so I'm already stressing out about how we care for him next time. He looks a lot like this young man's cat.
I wanted to get one of those fountains for our kitties, who just won't drink out of their own bowls, but my husband said "Oh for God's sake, they lick their own asses! Why do they need filtered water??" I had to admit he had a point.
