My intent is not insult or be "standoffish" with anyone, it`s just very frustrating at times when the same misinformation keeps getting regurgetated as being "factual" when it`s nothing of the kind, mostly just a personal opinion based on what someone told someone somewhere, with no evidence (tried and tested), so even more confusion abounds, which makes it almost impossible to get the most important messages across, as I say, these issues are literally life threatening to the animals. I do have lots of patience as I buy it in bulk, but now and again it gets quite low... I`m trying dsperately hard to help, nothing more to it than that, but you can`t please all the people all the time, sometimes you can`t please any of them! Good that you now inderstand why I mentioned sunlight! Most people don`t see it as supplementation, but of course it is just that, they (Varanids) absorb the UVB through the skin, which is a "back-up" for when times are hard in the wild, that`s what powdered supps are, too.Gravid females will form a large % of captives, the question to jarich was a very important one, and deserved a factual (tested) answer. I hope he`ll provide that at some point. The vast majority of keepers and breeders do offer some supplementation at certain times, even though their animals may be receiving some vertebrates.
