Vash will trance if I rub his head justright. I've tried to trance him on his back, but he won't gounder as deep compared to being upright. To trim his nails, Ijust lift his paws up one by one and cut them. He doesn'twiggle or anything. I never thought about putting him on hisback to trim his nails. My cats go on their backs, but myrabbit is too big for that lol.
