Ok first off im pretty excited because I changed rex's whole setup around, he now has t-rex desert snow substrate (i hope its good), and a new tree to play on. He has been hanging out in his tree and checking out his new toys all night. Ive had him for about 6 weeks now and he is about 18 inches, but he hasnt shed yet (keep in mind this is my first snake and im in love with him so im overly nervous about everything). Anyway, tonight, since hes had his new substrate, he has been in his water bowl, I mean completely submerged in it. Hes still very active, looking around and checking everything out, but does this possibly mean hes softening his skin so he can shed? I watch him everynight till about 3 am, I turn his main light out at 10 and his black lights come on, and this is the most he has ever been in his water. He was putting his whole head under, a pretty awesome sight if it doesnt mean anything else. I know that pythons get most of the hydrate they need out of their food and rex is a pretty regular eater (every 3-5 days he snags a mouse or two) so im not worried about dehydration. So what is he doing? Any comments would be gladly appreciated. I hope hes shedding I cant wait to see it.
