This isn't of high concern, especially since she is otherwise perfectly healthy, but every now and then (maybe 4 times since I first got her in January) I will check on my Colombian Imperator, or go to get her out, and she will have a few small pieces of coconut fiber stuck in her mouth, just enough to notice a small bulge in her lip. And it's never within 48 hours of feeding her - for example, it happened just now, but the last time I fed her was 6 days ago. I've never found this to happen with any of my other snakes, which are also on coconut fiber, just her.

Has anyone ever had this before? Anyone have any idea what's going on?
