we have had our tegu now for six weeks and I have not picked it up just keep doing stuff in his tank so he gets used to me, I also put a glove in so he gets used to it for the day i may be able to pick it up. He still hisses at me if I go too close to him, will this ever change he is so skittish still. Anyone got any tips (I also put my T shirt in that he likes to sleep in)
