I am building a new cage for my male bp who is almost 4 years old. Now he is in a tank that is 30 inch long by 18 inches tall and 12 inches wide. I have always been told that i would have to get a new cage for him to reach his full growth potential. So i am going to build a cage that is 36 inches long and 18 inches tall and 12 inches wide... I just figured that i would run the measurments by you all to see if the cage is going to be big enough... please help...
