[Gpdd] BEHAVIOR: Teeth grinding

[GARY HESS]

Today we were stretched out in the pig pen, and Hershey cuddled in close to me and was singing softly with her teeth chattering rhythmically. I thought that was supposed to be an aggressive gesture. I know rabbits grind their teeth when contented and also when in pain. Hershey didn't seem to be annoyed. Could chattering teeth have two different meanings in guins as well?
Hoping so,
