White Dust/Stain

[Lady_TOX]

Hey
My bun just became a mom about 2.5 weeks ago, since the baby started coming out of nest their has been a white dust like stain on her cage. Does anyone know what I'm talking about? Or know what I should do? I'll post a pic in the morning when my bun isn't in the cage.

Sounds like its dried urine? When it dries it becomes very dusty and leaves a white residue

So it's not her milk from feeding the kit? How do you take it off effectively?
