Hey all,

So I have just finish putting my snakes down for the year. Some were put down in mid-Oct, the rest today (6 Dec). Here is what I put down and the temps they will be exposed to:

Russian sand boas, Eryx miliaris
52-56F for 4 months

Smooth-scaled sand boas, Eryx johnii
52-56F for 3 months

Rubber boas, Charina bottae
52-56F for 1.5 months, then 38-42F for 3 months.

I also have one javelin sand boa, Eryx jaculus, that I put down because it has never taken a meal. He is being kept at 52-56F, and has been at the temp for 1.5 months and is still alive. Anyone else ever cool down Javelins?

For those of you that cool off you animals, what temps do you use and for how long?

Cheers,

-Chris

Chris;
I only maintain Charina bottae for research purposes so I try to mimic the conditions that transpires in nature. Consequently brumation generally begins sometime in mid to late October in most years as I allow the temperature and lighting in my snake shed to fluctuate with what occurs outside. The exception being that I have a space heater to keep the winter time temperature a few degrees above freezing.

Since some adult males in this region (Willamette Valley of western Oregon) can be found under surface objects in the month of February, in about mid to late February, I will turn on an heat source (40 watt bulb) over a hide at one end of the cage housing adult males. Some males will remain under a hide at the cool end of the cage into March whereas others will gradually be found under the hide with the heat source hanging overhead. The light bulb is on a timer that is set to mimic the light / dark cycle outside at that time of year.

In mid to late March, I will generally do the same for the adult females. Here again, some females will begin to be found under the hide with the heat source overhead while others remain under brumation conditions well into April under a hide at the cooler end of the cage.

For all juveniles and subadults, I do not provide any external heat source but allow them to emerge from brumation as the temperature conditions dictate. Most of these small snakes generally begin to become active sometime in April depending on temperature conditions outside and in the snake shed.
