In addition to what Derek eloquently said a little details on your animals would really help guiding you.

How old is your BP?
How big is it?
How big is your enclosure?
Are you hides tight?
What are your temps? What is your humidity? How do you measure them (What device do you use, digital or analog?)
How often do you handle your BP?
What are you feeding and how often have you been offering food?

The more details the better.

Now was the diagnostic made before the animal stopped eating or did you go to the vet because the animal did not eat and the Vet diagnosed him based on what you told him?
