[Gpdd] [BEHAVIOR] my little guys talking

Hi everyone...
I'm new to the list.
I have two young boy piggies (3 months) who I've had since they were about 4 
weeks old. I've noticed that when I (or anyone else) hold them and pet them, 
they seem to chatter a lot. They make little chattering or chirping sounds 
that's not clicking teeth and not wheeking, but something in between. I can't 
figure out if this means that they're content, or scared... To me it just sort of 
sounds like they're talking... Is anyone familiar with this sound? I've tried 
to listen to sounds online and compare, but with little luck...
