Ya know, while most of what Dragonbaron posted was ok, it just bugs me when someone thinks their way is the only way to keep a certain creature happy and healthy.
I've kept many species of tortoises, both desert and tropical. I've only intentionally bred sulcattas but I have raised up babies that I hatched and bred them so I am pretty sure that what I do works. Combine that with the fact that I've probably sold more tortoises, have established them coming in from the wild as well as getting good babies from breeders, than most of you will ever see, and again, I'm pretty sure that what I do works.
I didn't mean my prior post as a dig, too much, at Dragonbaron, but as I said, there is often more than one good way to keep the creature you want to take care of.
