Yes, it's fine for a while, & hatchling corn snakes are so tiny, you're better off making your own hides...small clean cardboard boxes (cut a doorway), cardboard rolls from
paper towels, many things work. If cardboard, throw away & replace when soiled...easy!
I hope you know that corn snakes do NOT require the same temps. as BPs? Much lower...assuming your house is not cold, just heat (UTH) one corner (w/ hide) to mid-
80's MAX, rest of cage can be 70*-78*...they actually seem to prefer low to mid-70's most of the time. I currently keep 5 corns, oldest one is 21 years, & have bred quite
a few in the past.
You'll need pinkie mice, assuming you get a hatchling, & they'll be eating that size for quite a while. Corn snakes change color quite a bit from when they hatch, so go by
the breeder's pics of parents. (the snake's parents, not the breeder, lol)
Corn snakes are tiny, so that means they can escape thru tiny gaps and since they like to climb, make SURE your enclosure is SECURE. You do NOT want to
play hide & seek with a tiny corn snake, it won't likely end well.
