I have noticed that if I leave my stool in toilet (water) for some time (like 15+ minutes... and I am not doing it on purpose, I just forget to flush) a colored cloud starts leaking out of it. The cloud has brown/red/yellow color and keep floating just around the stool and doesn't color the whole water in the toilet bowl.
My bowel movements are fine and the poop itself has nice brown orange with no colored spots.
Could it be just the stool color dissolving into the water? Because after I while, the stool has more pale color (like its lacking its color).
I even managed to make a photo, but please be advised - this is a highly NFSW image and don't click on it if you are easily grossed out!
