I am under no obligation to help you. the only obligation I feel is to the well being of the animal which is now YOUR responsibility.
You came on here stating that you had done all your homework.
You haven't. A screen top is a no no with a varanid. If you had done a modicum of research you would already know that.
A 100 degree basking spot is insufficient. There a myriad of other issues with your setup.
There is not simple set of guidelines to properly housing a varanid. A very exacting set of husbandry standards must be met. If you did not do your homework, you better do it now.
Start with a proper heat gradient with the top basking spot no less than 130 degrees. Start with an adequately sized cage that both fits the size of the animal yet allows you to meet the heat and humidity requirements.
Your substrate needs to be able to hold moisture and allow for burrowing if the animal so desires. It also needs to be deep enough to allow for this behavior. Leaf litter over soil works well for timorensis.
Since timors are arboreal, using cork tubes layered under the basking spot can simulate a retes stack and provide the proper heat gradient.
Now, if you find my replies rude, so be it. Personally, I find it beyond rude to purchase and animal with absolutely no idea on how to properly care for it. The word I would use for that is "inhumane".
If you would like to continue to be ticked off at me, be all means do so. However, while you are fuming, do that poor animal a favor and get it's needs provided for ASAP.
