Brumation is obviously not necessary for all snakes.

But they do experience a cycle. Shorter days, cooler temps and in some cases a rainy season. Snakes have adapted to their environment and not all experience or need the same conditions to reproduce.

I choose to brumate my cal kings becasue where I live , it is what they do.

I have success with this method. You may have not according to what you posted.
