Weird stuff in bunny's water bowl

[bunbunadri]

There's bits of hay pieces that appear after he drinks water, which has happened for a long time! I didn't really think it was a problem as he's really normal. Drinking, eating and pooping normal. Attached is a photo. I did bring him to the vet for a check up and he should be fine but I'm worried. Does anyone's bunny do that too?

That is just miscellaneous bunny dirt getting in the water. Whenever they eat hay or lay head first on the ground, some dirt is bound to get stuck and then they drink and the dirt falls into the bowl.
Just clean the bowl morning&evening and all should be good.
