[Gpdd] Behavior: unhappy noises?

[Victoria Lee]

Hi,
I've had my Horatio pig for 5 months now, and he's gotten pretty used to us 
and seems happy. But often when I pick him up to love on him, when I settle 
him in my arms and sit down, he'll make that short, ah-ah-ah-ah-ah sound 
that some web sites use as an audio example of unhappy pig sound. Does that 
mean he doesn't like being held in my arms like that? He's fine if I set 
him down in his play area, or even set him next to me on the couch. I know 
I shouldn't try to be affectionate if he doesn't like it--he's just so 
darned adorable--does anyone know why it seems to make him not happy?
Thanks,
Vicky & H-pig
