That's from a baby ball python that's about 6 months old.

Usually when my baby balls mess up their paper towels it's much more of a yellow color than a brown. Is this normal/okay?

She appears completely healthy otherwise, though she's a bit of a finicky eater. She'll often drop the mouse 3 or 4 times before finally taking it and swallowing it (eating frozen/thawed). Other than that she eats every 5-7 days and has never refused food.
