When my pet passed her eyes did not close. Is this normal?
Yes, The closing of the eyelids takes muscle activity. Therefore, the state of the eyes when there is no neural activity is with the eyes open, fixed (not moving) and the pupils completely dilated. So when the pet dies the eyes stay open. Humans that have recently died also stay open and this is where the practice of putting coins on the closed eyes originated to help put weight on the closed eyelids so they would stay closed.
