You wondered about the growth rate of sulcatas on your other thread and I don't think anyone really answered you. Yes! They really do grow that fast. You don't have much time with it as a small tortoise. I hope you've figured out how you're going to keep a 100lb tortoise happy while being confined indoors during the winter. Lots of outdoor habitat ideas in the Enclosure section under the pinned topics area.
Yes I have an old garage and a nice size garden that I plan to keep him in , in the long term. I know the size of the garden is fine but I have not yet researched into the best methods / habitat tips to be honest as I just want to get the immediate future sorted first.
All I can tell you is that we will provide our sulcata a great home for sure.
