I have thought for a long time that the practices I see people use to brumate could really be causing some common health issues associated with that time of year.
The bottom line is that I think cold and dry is a dangerous combination. And one that is not natural. If a snake is cold enough, I think that its highly possible that they will remain torpid despite dehydration. Too cold to go get a drink from the bowl. In the wild they don't have to wake up every few days to get a drink because they choose consistently humid locations to weather out cold, drought, famine, etc.
I talked to a good vet about this and he thought based on his experience that it was plausible, but that he didn't have actual numbers to back it up.
So now you have a snake that is dehydrated, it mucous membranes, especially in the respiratory tract take abuse, and to compound it you have an animal with a severely suppressed immune system.
By now I think you see where I am going with this. It brews for a while, you turn on the heat, and the snake wakes up from hibernation only to immediately succumb to a respiratory infection.
I always used "humidity chambers" for snakes that wanted to cool off for the winter. And I have never had a URI. Not saying that a b=c... but I am just saying. This year I will be trying new set ups described in the post below.
For those who have experienced URIs coming out brumation, I would love to hear about the husbandry leading up to it.
