Alright, well my iguana started eating a little more today. Still not as much as it used to, but a bit more. So strange that it started eating after I turned DOWN the temperatures below what is normally recommended.
Anyway, he has been doing this thing for about a week, where he burrows under the newspapers on the basking platform at night before it sleeps, right the moment the lights go off. Today, it did it in the afternoon as well. He does have a hide box elsewhere in the enclosure but he never uses it, only stays on his platform pretty much 95% of the time. I do not think it is because it is gravid because its stomach is all empty and it isn't really constantly digging around it just sort of digs one or two times until it is able to dive under the newspapers and then just lies there to hide (correct me if I'm wrong).
This is all fine and good. If it wants to burrow, it can burrow. But it is causing problems because occasionally it wiggles around a bit after it gets under the newspapers to get comfortable, and today, as a result, the water bowl went splashing on to the electrical plugs for the lamps.
Knowing that it has pooped already today, I have removed the newspapers temporarily.
I'll get a heavier bowl tommorow, but it IS getting a lot stronger. Also, do let me know if this is an indication of some other underlying problem. I don't know if I should be putting the hidebox on the platform but then EVERYTHING will be on the platform it would be stupid and make him a couch potato that I may as well keep in a 20 gallon.
