I hate to remind you, but snakes grow their whole lives...they just slow down when they're older. And he's not even very old yet...he's what? about 5 years old? Remember how so many kids outgrow (get taller than) their parents?If it makes you feel any better, I thought my FL rat snakes would stay about 6' too, but that was a foot ago.
Snakes don't listen to us, evah...
