some hiss and some roars
yes.... they start to hiss and perhaps even bite.
They make aloud screech if they just got hurt. If they don't want to be held or touched, they let out a long meow or a sharp loud one. I have three cats. And one isn't very nice. If the cat's wimping they let out a low meow you can tell immediately that the cat is hurt. If your cat is angry or scared, it might growl or hiss at the thing it is mad at. or if it is scared it might puff up its fur to look bigger.
