It doesn't matter how long they are and it doesn't matter how old they are. Also, Vander already said the female has not eaten since October.

Hi Vander~ Could you tell us about the size and type of the environment(s) they are in? What are the temps? Do they have hides? Are you housing them together? How is your heat controlled?

So often there is a simple husbandry issue that is responsible for a snake not eating. The more information you can give regarding their set-up, the better we might be able to spot something that you could change and might bring forth eating success!!

Looking for ward to learning more
