Thanks, Bill M., for the compliment. I really try to make Simply Subocs helpful to the suboc community.
I will copy and paste something from a Facts/Myths page that I wrote for subocs.com (that isn't up yet). It's very general, but I hope it helps, because I've included some of my own observances of captive animals.
The bottom line why I think it is not good to leave water out for more than a couple days is that we don't know what the snake is thinking, and it is always best to give captive animals as many options as possible. If it were possible, I would have several hiding places in all of the cages...one that is damp and cool, another that is damp and warmed, another that is dry and cool, and yet another that is dry and warmed.
Wild subocs sleep in humid and damp environments, and the tick that plagues them in the wild needs dampness to survive.
So I don't believe humidity is the issue.
As far as the chlorinated tap water, I'm not aware of any studies that have confirmed that it is harmful or beneficial, either way. If we don't know, but only speculate, then that may need to be studied in a lab somewhere. But let's keep in mind that many subocs have thrived for YEARS on tap water. The captive record for a TPRS is 23 years, I believe. Doug Mader's herp medicine & surgery book shows another "H-snake" longevity record of 18 years.
With that said, I'll copy and post what I have written below:
“Do subocs always need water in their cage?”
From my observations, absolutely. Certain individuals in my collection “drink like a fish” as soon as I replace their water if I had removed it from their cage for more than a day. With other subocs of mine, it doesn’t seem to faze them much if there is no water for a couple of days (but no more than that, mind you).
I mention this because some of the early literature on TP rat husbandry speaks of some keepers who kept their subocs without water except when it was offered maybe once a year. They thought this was good for them.
My guess is that a lot of keepers, even as early as 15 years ago, did not fully understand the humidity/ventilation issue the way we understand it now. It isn’t as important to keep a water bowl out of the cage as much as it is important to keep fresh air moving in and out of the cage. That is why A/C is usually a must in a humid location.
In fact, all of the successful breeders that I speak with keep the water bowl in at all times.
