Red splotches on the belly of my female ball python:

[necoris]

I have noticed that one of my female ball pythons has some wierd slightly reddish splotches under the entire length of her belly. They are hard to see in the picture, but they are there. I know she doesn't have scale rot (which looks totally different) but I was just wondering what it could be.

Here is the picture:


Thanks for any advice,
Dustin
