Here's a photo of Lucy, my 50% dwarf reticulated python. I've been keeping her on coconut husk substrate and last week I let it dry out a bit too much and when she ate her rat she got a piece in her mouth. I'm thinking it stained her face a bit since that stuff stains the water brown. But after looking at this photo I was wondering if she just has a dirty face from the coconut husk substrate or could it be damage from rubbing (or both)? Has anyone seen anything like this before? Maybe I need to throw her in the bathtub for a bit with some warm water to clean off her face? She almost weighs 30 pounds now!
