I think my RFT's shell is rotting.....:-/ On his tummy there are two large circle-like parts where his shell is cracking off almost. I could take my finger to him and pick at it! WHAT DO I DO???? I called the vet and they said "as long as it's not soft I should be ok" and that he's probably "fluffing"....WHAT DOES THAT MEAN???? The spots dont seem soft, but it's definetly a different texture. Please Please Help me!
