I was just reading in the tail debate thread about holding chins by the tail. I am still not used to it as i still need to learn the right amount of grip, as he often slips and i let go so not to break his tail!! BUT thats not the thing. Whilst there a lot was mentioned about holding the chin by the tail upside down? and many said it calms them down...what is this? never heard it, could someone please explain?
