Hi,
It takes practice for sure - and with the big girl I have she tenses up so much I can't feel anything (she's a bit of a nervous nellie).
When they are smaller they seem to lie pretty much along the center line but as they get bigger they do seem to have to move slightly offset to one another to fit in. So near the end I always seem to end up feeling them like this;
But having the snakes belly be relaxed seems to be the most important thing - if they cooperate you can feel them as small as a marble very easily.Code:o o o o o o
If they don't cooperate you can be struggling to feel anything at all.
