Grunty-hiccupy-groany noise when stretching.

Buckley just made the weirdest noise, I've never heard him make it before.
You know when you're yawning and you do that "nyahhh" bit at the end, it was a bit like that but more "nyurmmm" once when stretching.
Kind of coo-y too. It was a really odd noise.

Your littles 'nyuums' and 'nyaah's made me giggle :lol: I've never heard any of mine make a noise like you describe before.
