hello everyone, i really need your aids



here are 2 pictures of my ball python's urate. the green stuff looks really rare.
it's wet. the white part is charky.

my ball eats normally every 5 days. last time he(~200g) ate on sunday, a rat weaning

substrate temperature is 82-92F/28-32C. he's still active and looks normal.

what would cause the green looking urate...?

thanks a lot!!
