You do not have to brumate or hibernate to breed them or otherwise. That is merely a manmade misconception.
Reptiles require a range of temps to complete their lifes, that is what makes them different then mammals. Left to their own(in nature) their lifes are nothing but making temperature choices. Their lifes in moving from one condition to another.
If you allow your snakes/lizards/torts, etc, a relatively small range of temps. They not only breed on their own, but they WORK and LIVE, longer and healthier.
For instance, if you keep snakes are a room temp of 65F and have part of the cage(basking area) around 100F. And(an important and) They have the ability to move to and away from both, YOU as a keeper only have to feed/water them when they are hungry and clean cages. Then you can sit back and enjoy the animals for what they are. You know, to watch them use their own nature and inherent abilities.
You do not have to do everything for them. I, as an example have kept and bred generations upon generations of various reptiles for many many decades. Many many of those species were thought by unaware people to "REQUIRE" hibernation. Many many, of those species were world first breedings, yet, I did not hibernate them.
You see, reptiles normally "REQUIRE" cool to conserve energy, and warm to "USE/EXPEND" energy. So naive keepers get the idea that reptiles do not know how to do this. So they do it for them. The "TRUTH" is, they, the reptiles are indeed expert are regulating their own temps, IF GIVIN the oppertunity.
To answer you question, you do not have to hibernate your snake. But it would help you to understand that your snake "normally" picks a range of temps to lead a normal life.
With kingsnakes, its only a small range, 55F to 65F cool, and 85F to 100F warm side. Of course, snakes rarely elevate their body temps over 85F, but their are two REAL values to allow them to achieve hotter temps then normally needed. One is, they use higher temps to increase or build up their immune system. And two, they use hotter temps to break down large prey items. They only need these higher(higher then 85F) for short periods. These are only two examples, there are many more.
Many keepers somehow feel the need to narrow the temp range to a horrifying average. You know, a temp where they work, but not all that well. Please consider, this is about the keepers and not the animals. Theres nothing wrong with it, but again, its not really about the animals.
I hope this helps and no offense to those whos toes feel stepped on. Cheers
