Uterine Prolapse in domestic rat

I took this photo in case it could be helpful to someone else with sick rats, I couldn't find much when I was frantically searching the net at 2am. It's not always very pronounced. The protrusion was slight but as you can see her entire vaginal area was very open, which is abnormal. There was also discharge, but no blood.

 

The vet and our rescue coordinator made the tough decision to put her down. At her age the exploratory surgery to diagnose the source of her prolapse would have been an extreme risk. RIP Susu.
