Well her initial blood work came back clean, so there doesn't seem to be anything wrong with her red/white bloodcell counts, liver, kidneys, or other major organs. We are still waiting on the Thyroid test. If that comes back clean, the vet suggested I bring her back in for a re-check in a month. It is possible the murmur won't be there next time, and if it is they can do an ultrasound to determine what is really going on. It does seem like there is no immediate danger since her vitals were all normal yesterday as well.
Update: Her thyroid hormone levels were a little lower than normal, but apparently association with heart conditions is only when the levels are higher than normal. So, we are at the wait and see stage.
