I have to know how much do you think a tegu will grow, during there active season. Lets say your tegu is 21 inches at the time of hibernation, then when hibernaton season is over he/she begins to feed regularly. How much do you think your tegu would have grown by the next time hibernating season comes around again. Anyone who has a personal experience, with keeping up with the growth of there tegu from season to season, please let me know what the results were?
