guinea pig noises

[shazbo]

what noises do they make when happy sad angry . when i went with daughter to pick the ones i want i held one and his little heart was beating like mad after awhile started making like a purrring sound and went for a climb on my shoulder under my hair

Purring is contenment. If they rumble it can mean she is a bit weary and frightened sometimes they don't like you touching their rear end. My boys are like that.

Ok, I found this website, there are some examples of sounds. This way you kind of have an idea as to what they sound like, and what it might mean.
