I have 2 Bengals and 2 Siamese. If you want a quiet, easy going cat, than a Bengal is NOT for you. The are super active, and they jump and climb A LOT. My Simba is constantly getting into mischief, and he's a lot more stubborn than my Siamese cats. He's a sweet beautiful boy, and he's loads of fun, but he's a lot of work. He is always in to everything. He's also very vocal, even more than the Siamese cats. If you don't want an active, in your face cat, that requires a LOT of attention, I would suggest you don't get a Bengal, just based on the looks. You'll end up being unhappy with the cat. If you want a cat that wants to play a lot, and wants to play fetch like a dog, and you have the patience to deal with the little messes they make like knocking things down contantly and getting into everything, then a Bengal will be a great cat for you. Bengal's are lots of fun, and a joy to have around, but they are NOT mellow, and they are not for everyone. Bengal's require a lot of attention. My Bengal boy hangs out on the tops of doors and climbs any and everything he can like it's a jungle gym. My female Bengal Angel, is much more mellow, but I think it's because she's still not used to my home, yet.
If you do end up getting a Bengal, you'll need to Bengal proof your home, and keep delicate breakable things out of harms way, because NOTHING is safe from a Bengal getting into it.
