I have two gorgeous little guinea pigs that I have had for a week now. Both are doing really well and seem to like their new cage, the food I give them etc. I pick them up when they are in their tunnel (like the video thread suggested) but I still don't know what all the noises and movements mean. Lavender seems to be happier to be held but I have noticed that she kind of vibrates when I hold her. She doesn't seems to make any noise that I can hear and she sits quite still. Is this her purring in happiness or is a unhappy vibration? She isn't frozen in shock and I think she likes being held. I have looked at the thread that seems to explain behaviours but I couldn't see a description for Lavenders behaviour!
