Well, you've come to the right place. I only hope you've reached us in time. There are many reasons for a tortoise being inactive. We'll need much more information from you in order to give you our best advice. If possible, post a picture of the tortoise in its enclosure, and tell us what you're offering for food, what kind of lights, what the temperature is on the floor of the enclosure. Give us as many details as you can.
It`s a pitty how much threads are running into emptyness. Like this one too. @Jatin was never seen again since he wrote this thread. Like a lot of other ones that are searching for help.
I fear that a lot of tortoises must die because of this.
Poor, poor torts !
