Heres the deal. That person READ that in some old totally out of date book. So, like a test in school. That person is right, he read it and repeated it to you. But the information he read was wrong. So with current information, that person is WRONG. Of course he was right, if you keep them poorly and feed them foods they are designed to eat, they will die. But then they will die anyway from lots of other things.
In the old days when they recomended and offered tiny little or no basking areas,90F minus, monitors could not properly digest and assimulate heavy(whole) food items. But with more natural basking spots,135F plus or minus, the temps these animals were designed to use, they not only have no problems, but grow, live, and reproduce very well. You know, the things that old information monitors TOTALLY FAILED TO DO.
With that old information, Savs commonly died of fatty liver disease. The reason is very very simple, the monitors were running a half speed and that will eventually cause organ failure.
In the old days they NEVER reproduced. In the old days, they all died, PERIOD. Now a days, only most die, not all. The reason is, people somehow still read and believe information from those that never ever, never ever accomplished anything with monitors. Don't get me wrong, their accomplishments were writing. Sadly, the writing did not have to mean anything or be right. Their merits were what they wrote, not what they did with monitors, or what their information caused to happen with monitors. That is very important to understand. Please understand the context of the time. If all your monitors failed and died, what are you going to write about?????? Anything but the actual monitors, and so they did.
I am ashamed of you for even giving someone without any actual accomplishments a second thought. You do understand, people have the need to say something and they do. Your task is to ask the right questions and MAKE those people prove their information is correct(realtime current results)
The main and central recomendation is to listen to your monitors. If your monitor is doing well(for the moment) why would you listen to a nameless faceless babbling icon.(what Jobi said) In that, your wrong. And yes, there are people with real complication, indepth well writtin BABBLE. No matter how good their babble is, they must still produce results. No results, equals babble.
Don't listen to people on the internet, that cannot show you with the actual animal. Thats the value of the internet, to have real up to date realtime information. Not something someone read in a book. You can do that if you want. Anyone can.
About books and papers. They MAY in right for the time and application(context). But all books and specifically scientific papers are designed and meant to be REVISED and CORRECTED. So check the date/s, check the results, and weight them with the CURRENT levels of results. Really, you wouldn't pick up a book or engine building and modification, written the the fifties and apply it now, WOULD YOU?(at least those old motors worked)(that old information on monitors did not work then)
Sorry for being so long, but it seems people refuse to understand that information on husbandry is DIRECTLY related to the results of the ANIMAL its suppose to be applied too. Not based on how it sits on a sheet of paper. Its judged on the results the information produces.
One last thought, whats important in captivity?????? This is a very odd question with lots of answers. Is lenght of life important? or is quality of life important. It appears to me, most here dwell of preventing something bad happening in the future, BUT TOTALLY forget to give the monitor a life now. In my humble opinion, their lifes do not start until they actually do things they know how to do(TO LIVE). Sitting in a box and having a heartbeat is NOT A LIFE. its torture.
I personally think doing the base things animals do(life events) is whats important. You from your pics think flopping the poor animal on your shoulders and carrying it around is important. Both are better then nothing. But you could do both. Cheers
