Had to check the other thread to see what animal you were talking about, guessing its the BW tegu you spoke of. Well aside from genetics which plays a big part on the growth of any animal, Husbandry plays a big role aswell. Temps, Food, Cage size (exersize)...etc. Ive had a BW tegu grow aprox 2.5inch a month on inverterbrates and fruit diets with very little fuzzies everyonce in a while. Then once he started on mice consistantly he started putting almost 4 inchs or more per month. The two ive had seem to hit their growth spurt at the six month mark, they start putting on size like weeds, HEAT em and FEED em...
