My tortoises are so happy outside!! I really want to build a good looking long term out door enclosure but all the ones I have been looking at have larger tortoises in them. What age is a good age to have a permanent outdoor home? I live in the middle of Texas with two 3-4 month old leopard tortoises. They currently have a 4 by 4. Tortoise table but they just arnt as happy and when they are outside.
