it was fine 2 days ago and now it wont even move. other websites say that if it is alive then it wont allow me to pull on its legs. my tortoise dosnt do anything when i pull on them ( slowly). I dont know what could of happened in the last 2 days to cause something so dramactic. I have had it for about two yrs. now and it has never done anything like this before.
