I would not recommend that you do any surgery until you have the liver shunt issue completely diagnosed and treated. Until you have a final diagnosis on the liver shunt, you can use panties on your little one when she is in heat. It is absolutely essential that she not get pregnant if there is any possibility of a liver shunt. Your priority at this time has to be resolving the liver shunt issue.
