I wanted to explain how the ears on that photo you found of a Bengal are not right, but I looked up more info before I said something. I knew the Bengal ears are supposed to be small and rounded, like on my Bengal. Here's a good explanation of what I'd wanted to say: http://solanaranchbengals.com/bengal-cat-type.html
The ears for the most desired Bengal cat, the wild "type," would be small and rounded, not like the cat in the photo you found. Unfortunately, it took after the domestic cat genes to get those ears shown in the photo. Actually, most of its characteristics look more domestic than the more desired wild asian leopard cat's type. One thing this site didn't mention was the Bengal nose. The nose should be big & broad in a perfect Bengal cat. My Bengal has a large nose in keeping with her more wild "type."
