my eight month old star tortoise passed a kidney stone jus now it was the size of a lemonhead(candy lemon balls) i understand that this happens,i read about it in jerry fifes star tortoise book but i didnt realize that it would happen so soon,is it sumthing that im feeding him or the amount of food ive been giving him cuz he eats alot,ANY HELP WOULD BE APPRECIATED.......also is there sum sort of preventative for this,i mean i could tell he was straining i jus thought he was pooping so i picked him up and i could see it lodged so immediatley warmed up water and placed him back in to soak and i guess that helped cuz when i looked there was a white ball.
