My sister had 5 sulcata babies that were outside some of the summer. After a month or so they started getting soft bellies, quit eating and 4 of them have died. One is still alive, but it is not eating now and its belly is soft. The breeder of them has told her when this happens they probably ate something that was toxic and there is nothing that can be done to save them. She was told that by the time they appeared sick the damage had been done to their insides and they could not be saved. Has anyone had this problem and what did you do?
