Ok- so first I just want to say I realize that my views on this are not the "norms" on the board here. But they have served me well for 20 years and most certainly were "normal" 20 years ago when I started breeding veileds.
Secondly, I want to say that I respect both Kinyongia and jannb. I disagree about temperatures, but understand their reasoning (or at least I try my best on this one). And I feel certain they care about and their very best for the health and happiness of their animals. And their very best is better than most of ours.
I do disagree that longevity is everything for the thinking I already mentioned about comfort alone- a chameleon unable to select it's own operating temperature is going to crave it and select it if it is ever given a chance. To me that is enough- I trust the lizard to know what it is doing when it comes to thermo-regulation if it is given the choice.
I'm not convinced either that everyone can keep a chameleon's system running day in/day out on low and still keep that chameleon healthy and disease free like kinyongia is able to do. I'm also not sure that stopping reproductive cycling is always the healthiest option- certainly in most animals including humans it indicates there is a problem (stress, disease, diet, etc). I'm not certain by any stretch that is so with these cold kept chameleons (other than the "problem" of being too cold for the reproductive system to function), but on the other hand- if I were to treat an iguana like that or any other basking lizard that normally operates at warm temperatures given it's own free choice I would expect problems over time.
Maybe chameleons are different- maybe not and maybe a very talented individual could take an iguana and treat it like this and it would still remain healthy. But in the end- if the lizard is given a choice of a wide range of temperatures, it will choose a temperature without us forcing it on them. For me, that is enough.
So that is my thinking anyway. Like I say, I disagree but have respect for others successful experiences.
We are not raising them in the wild so we need to make alterations to the care to try to compensate for it. We do not have the same cage conditions that their natural habitat would provide nor do we feed them the same variety of insects/food that they would get in the wild.
This is true, but this is a double edged sword. We could take this and twist it into any husbandry we want once we say the terrarium and husbandry are unnatural. Even very extreme and very wrong husbandry could be justified by this logic. (ie- we need to compensate and they aren't in the wild eating a wild diet so we feed them mice daily to ensure they get adequate nutrition and all their vitamins. After all mice are a complete diet for many herps. Very wrong but justified by the above logic.).
Thermoregulation is natural and almost like breathing or hearts beating for a lizard and occurs in the cage or out of it.
I keep the babies at more moderate temperatures because their bodies can dehydrate
This is a good point and one that I forgot- care must be taken to ensure they can escape the heat. I'm not advocating all hot cages, just warm basking sites and a true thermo-gradiant within the cage so they can move in and out of a spectrum of temperatures from very warm to cool- they will do that to avoid dehydration. But also with very small babies under a month old or so, care needs to be taken to provide plenty of moisture at least a couple of times a day if one is using my method. If a hand sprayer is used for only very brief periods of a minute or two, then several times a day
, warm, cool more rapidly than adults can but also because it slows the metabolism a bit to slow the growth so that the chameleons will be less likely to develop MBD. IMHO they have more chance of developing the MBD when the growth is rapid because many people don't seem to be able to supplement the insects/gutload/feed the insects appropriately enough to prevent the MBD/keep up with the growth.
If proper supplements are used there is no risk of MBD. If inadequate d3 is provided either via lighting (preferably) or supplementation or both, there is a risk for certain. But there is with slow grown animals as well. If adequate supplements and lighting are used, the animals will grow rapidly and healthy as they are supposed to. My best guess is that wild veileds grow as quickly as possible so as to move up the food chain as quickly as possible- being small is dangerous business and can get you eaten, cooked, dehydrated in the wild. Just a guess.
I would never keep a 3 month olds basking temps at 90.
I keep them with higher temps than that available from day 1 and have *never* had a problem from it in 20 years. I don't think that is luck. It is the chameleons knowing what to choose and what they need. I don't force any temperature on them- I let them choose from a wide range. They can avoid the 90 if they want- they won't though, given the choice they will use it and it will be no problem as long as they have a wide range of other temperatures to choose along with it.
By 3 months old anyway- my veileds are several inches long (in the old days even longer sometimes) and at a size that is very durable.
I truly love my chameleons and would never do anything to them to make them unhappy or harm them. I keep the lower temps because I want to do what's best for them.
That's very interesting- I feel the same way about mine and that is why I use the higher temperatures for basking.
The difference between us is I don't force my chameleons to be warm or cool- they get to choose what they want and they are biologically programmed to choose what they need. I have confidence in their ability to do this. If you want them to be happy- offer them an opportunity to bask at your current temperatures and offer them basking opportunities in the 90s and watch and see if they decide they are happier basking in the 90s some times (like mornings, or after mistings, or after eating). That is my thinking anyway- maybe your definition of their happiness is different- maybe the lizard's definition is different than both of ours- they aren't talking. All I can do is offer choices and trust they know what makes them happy for themselves when it comes to this.
One last comment and then I'll bow out of this discussion and you guys can go back to advice as usual here without my input- I sometimes bite my tongue to avoid confusing new owners but-
The original query was why is the veiled basking more than the panther. The reason is because it is trying unsuccessfully to raise it's temperature to the level that it wants to operate at. So it stays in the warmest spot waiting and waiting to warm up. And that is simple truth.
I leave it to you guys to draw your own conclusions about the happiness or comfort level of such a lizard and to balance for yourselves the health benefits of preventing the lizard from achieving the temperature it craves, and whether lack of reproductively cycling is a sign of unhealthiness or not and whether the longest possible life is the ultimate goal of good husbandry in spite of a craving for heat that goes forever unsatisfied.
I have some strong opinions on this stuff, but I readily admit that my experience is one sided- I have not been able to try the cool basking temperatures over the long haul. And I also readily admit that I wish I was in a situation where I could try it with several females so I could re-examine my strong opinion in light of personal experience.
Maybe for a pet female where reproduction isn't desired, the cooler temperature and an extended lifespan is desirable.
But none of this changes the answer to the original question as to why the chameleon is spending so much time basking. Extended lifespan potential or not- it is craving a warmer body than it can get under the current situation.
