Some are quieter than others. Sky is a Norwegian Forest Cat/Siamese Mix and he's very quiet and has a little baby raspy voice. Starr is fairly quiet unless he gets excited and then he has a very high pitched squeeky voice. Pearl must have a lot of Siamese in her because she's has a very loud voice and is very vocal and chatty. Sunny is an Aby mix and he's also has a loud voice and loves to talk even though he has only a little siamese in him.
