No, the savanna cats do not hiss like the snakes.
Snakes in general (not just pythons) usually hope to scare off an attacker when they hiss. A tame captive snake shouldn't hiss unless it is ill with, say, an upper respiratory infection, in which case it would 'hiss' upon exhalation.
No - the don't 'chirp' ! The only sound they make is the occasional hiss.
Almost like a snake, snakes hiss because it means their defending or their gonna get ready to attack.{PEACE}:O
Snakes hear through their ribs, the part of them that resonates with the ground. This is why it's so easy to trip over a sleeping snake. They don't communicate vocally with other snakes. "Hiss" is a popular conception of a snakey noise. Snakes generally try to make no sound at all since their livelihood depends upon sneaking up on things. This is one cause of other creatures' fear of snakes: you can hear a wolf or a wildcat coming, but a snake is just suddenly, silently there and, very likely, wishing it was a long way away from you, but those unexpectedly sharing space with a snake don't see it that way. Rattlesnakes and their relatives do make noise, but it's a defensive reaction designed to make things too big to eat go away.
