Keep in mind these images are bigger than real life...a little shed left on a tiny tail tip is truly very hard to see, so use a magnifier if you need to. My snakes don't
"appreciate" me messing with their tail tips if any shed is stuck, but I've never had one bite me for doing so, they just get squirmy & try to leave town. You have
to be the grown-up.

On the top photo you see a darkened area, but at first, you won't see that at all...just a bit of shed left on the tip. It's important to get the old shed off before it gets
to this point, because if the tip dies &/or becomes septic, it's a bigger deal, a vet may have to surgically remove the tip so the infection doesn't become systemic (thru-
out the snake's body).

That's a very helpful post, for sure...
