Heather did you ever figure out what the extra heat pits may be? Well for some reason I looked at my Mojave pair (2008) and a 08 Yellowbelly and so far all 3 have these funky holes....
I don't think they are possible issues from the newspaper that I use for bedding. I use to use white mat paper from my printing company then for some reason I don't know why I started using newspaper and saved the white for my albinos. I do know that they all seem very sensitive in this area like they are actually holes and are painful. I am going to e-mail Ralph at RDR to see what he thinks it they are.
