Kidney stone?

[Geng]

Hello guys,

I was cleaning the enclosure of my Russian last night (male, around 7 years old). I saw some whitish/grey thing in dirt. I thought it was a piece of her endive or poo. I picked up and it was very hard and solid, like stone. I washed the dirt off and it really was a piece of stone. I never encountered stones or anything in the enclosure before. I clean the enclosure daily and moistes the subrate weekely, but never saw any stone.

Does this look like kidney or bladder stone? Does anyone have experience with it? It looks really big to pass, so I really hope it is not a kidney stone. My tortoise is acting normal. He is active and has a good appetite.

It does not look like a bladder stone. Here's a photo of a bladder stone, they are more white and chalky in appearance:

Bladder stone/impaction?

So while giving my baby sulcata his/her evening soak and i started to realize that at one moment i saw the lil guy hold still in one position in the soak (warm water with uva) as if he/she was trying to push something out and at the end around 15 seconds later his/her head instantly goes into...

Are you using actual dirt(soil) for substrate? If so, this rock was most likely already mixed in with the dirt and you just did not see it. A tortoise might try to eat something like this. Many people use fir bark/orchid bark/ZooMed Repitbark for indoor substrate to avoid potential problems like rocks.

I use coco coir.

I seriously hope it is some random piece of rock I have never seen. Also it is quite big for him to pass...
