I happened to look while i was holding my tegu that it's tail was wagging...at first i thought it my be the wind blowing through the window but a couple days later it started doing it again so i quickly put him back in his cage and i left him there for a day. then the next day he started doing it again, then i left him alone for a day then i pick him up out of his bath today and he started again, he wasnt hissing or thrashing about. Just his tail swing side to side, i was wondering what this means or if i'm crazy can't keep a steady hand.
