My female pet rat

Question
My rat has something protruding out of the area that looks like where the vagina is.  I think its prolapsing.  She is acting normal, eating and drinking well.  It had some pink discharge from it a few days ago.

My other female rats head is tipping to the right.  She walks straight and seems normal otherwise, no tumors noted and her eyes look normal.

Answer
Your female rat that has the protrusion from her vagina probably indeed has a prolapsed uterus. She needs a vet right away.

The second female has head tilt from probable ear infection that can be easily treated with antibiotics and steroids.  Please check out my website about head tilt and how it needs to be treated here at this link:
