Because they don't feel offended or scared. Cats hiss because they feel danger. If your cat or somebodies cat you know isn't hissing. That simply says that they are happy. Happy to help!!!
some hiss and some roars
some do, some dont
Yes, they both hiss.
I'm sure they can but that's if the big cats don't kill the little ones
some people believe so but no a cats kiss does not have venom in it
Yes they do when you upset them
Cats meow, hiss, growl and purr. When mating, they may also moan.
No, the savanna cats do not hiss like the snakes.

Yes, but they do not have vocal cords. Their breathing organs (while breathing) emit a hissing sound.
I've never herd a cat bark, but they do make a growling sound and they hiss and meow.
