Afterthoughts:
I doubt that you can feel the bite of a hatchling corn snake...I sure can't...it's like being pecked by a small sunflower seed, their teeth are too small to feel.
Some act more defensive than others, but they catch on pretty fast...they'll be tame (not trying to bite) LONG before you can feel their teeth.
I'd avoid a reptile tank with sliding lid: most of them have just a bit of wiggle room that a tiny snake like a corn can escape thru the track. It happened to me
years ago, only it was a similarly-sized hatchling king snake...the sliding screen was locked but that little stinker slid out anyway. (I found him in a boot in my
closet...) So if you use such a cage for a hatchling, be sure that every time you open/close it, you tape the corners so the screen has no wiggle-room & cannot
move even a quarter of an inch...'cause that's plenty for escape.
One thing the hatchlings really like is shredded & fluffed paper towels to hide in (torn in strips & tossed like a salad) makes endless hiding but easy to move thru. And paper towels for substrate have traction...newspaper does not & that's why I never use it, even if it wasn't so ugly, lol.
But there's no single "right way"...many things work for corn snakes, & when they get bigger, they love branches too.![]()
