Often, bad automatic transmissions will emit humming, buzzing, or whining sounds; manual transmissions emit harsher mechanical noises, such as clunking. Some of these noises may relate to the engine, exhaust system, drive shaft, differentials or even a wheel bearing.
Rattling Noises. Your catalytic converter consists of small, honeycomb-shaped components that can cause a rattling sound when broken. If your catalytic converter is broken, this rattling should be loudest when the car starts, and should get worse over time.
They don't like it, because it's their way of “saying” to somebody they are pissed. If it's not your cat he will probably back away, or straight up run away. So just don't hiss to a cat, unless you don't like it.
Growling and hissing are both very common ways that cats communicate. A cat growling and hissing is usually a cat who's scared. When your cat growls and hisses, he's effectively saying, "Back off now, or else." Usually, a growl is just a warning and he won't actually attack.
