Koko the Dumeril's Boa - Deeply beloved, suddenly passed

Nothing found in histopathology results either. It seems that I'll never know, which is also pretty upsetting.

I'm truly sorry to hear about your snake koko i think finding nothing wrong is a good thing "in a way" because atleast she wasn't in pain when she passed?, I think of it as like somebody passing in their sleep. just my two cents, again sorry for the loss of your pet koko.
