I was petting my bunny, just petting and holding his ears gently in my hand while stroking it, and he vibrated around his head area??? : r Rabbits Why Do Guinea Pigs Vibrate? When I cuddle my bunny & pet her she'll like vibrate & make a noise that sounds like a cat purring but she'll stop when I stop is something wrong with her? I just got my sweet boy today, he's a few months old. As I was holding him he was warm and snuggled but he was doing this head motion. Is this a thing??? I was worried for a minute but he's acting She is shaking so much, is this normal? My bunny seems to be shaking. Is this normal?
