Forgive me if I've cross posted this anywhere. I'm new,and I don't get any of this. :[
Alright, I'm in need of help here, and I have some pictures if anyone wants to see what I'm talking about, you can email me at littletragedy@yahoo.com. Here's the deal: We've been dealing with vields for a while now, we used to breed, then we got too busy and gave up the chameleons completely. Well, a few months ago, we got a male vield chameleon. He's great...or at least he was, up to a few days ago. Over night, my boy Sam, became aggresive and scared of us. He's done nothing but hide, and he's surely freezing, he hasn't gotten any light until today when we forced it upon him. He used to take silkies from our hands, now he won't even eat, and he hides the second the cage door opens. He had 2 silkies (MAYBE 2, more likely 1) on Wednesday which is way less then normal. He'd normally eat 3 silkies and a dozen crix. And Thursday and today, he's eaten nothing. His eyes are beginning to look a tad bit sunken and he's definately skinny. We've been drenching him in water, but he just hides again. His colours used to be fantastic (that's the picture I'm talking about) but now he's gone all brown, black and yellow (I've a picture of that also, for comparison, if you'd like). His colours may be dark because he's trying to get heat, but I can't figure him out. I'm just stuck and clueless as what to do with him, and my mother's sure he's going to die. He used to enjoy coming out of his cage for some outdoor sun, but he hisses and hides now, if he wasn't hiding already (which is unlikely, that's all he does). We've covered his cage, but he's sticking in one corner, so we've set his lights up in that corner. God, I'm clueless. This has never happened with my other chameleons, I'm at a total loss. Could it be like 'puberty' or, I don't know, help, advice...anything, I don't want to loose him. He's my baby
