loose scales?

I noticed with both my BP's that when they slither through my fingers, and I move my hands in the opposite direction of the scales, I feel that some are "loose". Not really LOOSE, but they may be lifted for a split second, and then it goes back down to it's normal position after passing through it. Anyone ever experience this? Is it normal?

EDIT: These aren't many of the scales, so it can't be a shedding problem. It's more like... 1 or 2 throughout the entire body.

It is completely normal.

Yep it's normal. I just would't suggest running your hands the opposite way of the scales. :D
