Question on corn snake feeding

[Bogertophis]

No I do not put him thru brumation at all (I guess this is not harmful?)

Pet corn snakes not intended for breeding do not need to brumate, & doing so can cause problems. When snakes are cooled down, so is their immune system, so if they
have ANY sort of 'thing' going on, they can succumb to that while in brumation, & either come out of it sick or die while in brumation. It's not risk-free, & they may also
refuse food for a while thereafter, because (as with many snakes following brumation) they're looking to breed first, way more than to eat.

So for NOT brumating him (or her).
