I've had my tegu Marty since February and he's about 1 and a half years old and going on 2.5 ft. I feed him every other day I either give him 2 medium sized mice or chicken necks. He's bitten me once and ever since I feel like he's a little more aggressive. It could be that I need to feed more often but I'll reach my hand in his cage to hang out with him but he'll lunge for my fingers. Is there anything I can do so gets used to me even more? I've tried the shirt trick and that kind of helped. I just want to be able to hang out with him like I've seen other tegus
