adrenal behavior issues

Question
I just read this Q&A:
Question
"Hi
We have a 4 year old fixed male and a 3 year old fixed female.  We have had them about 8 months now.

Lately the male will get on the top of the female and bite her neck hard enough to make her squeal.  It possibly could be a mating behavior but both are fixed.  We separate them when he does this.  

This behavior started about 2 months ago has been more frequent, probably every day now.

Is there anything that we can do to stop this?
Thanks

Answer
Sudden aggression is usually due to illness, possibly adrenal disease which requires surgery.  It isn't mating behavior - if they were newly together then it would be social fighting, but since they have been together for a while - take him to your ferret vet for a check up."

I have the same situation. However, I am moving to California in 8 months (where you can't have ferrets), and basically, I just cannot spend the money to fix his problem. He (Winston) has been biting Sharma in the cage alot (he never did this before)...in fact, last night it was so loud that they woke me up (from 3 rooms away).

Although she hisses when he does this, when I separate them, Sharma doesn't seem that mad, and ends up getting back into the hammock with him.

Do I need to worry about what might happen when I'm not home? Is she in danger of being REALLY hurt? Should I get separate cages for them?

Answer
I wouldn't necessarily worry that one will get hurt, but if the aggression is due to adrenal it won't get better and adrenal disease is cancer of the adrenal gland.  If the cancer grows it will damage other organs and become a fatal problem.   I would research vets in your area and see what you would need to spend to have the surgery before you move to California.
