I have two female piggies, both are about 2 months old. When I was playing with them on the floor this evening I noticed some hay stuck to the underside of one of my girls. I pulled it off and noticed a clear kind of sticky discharge from her vaginal area. She is eating fine, not lost any weight, drinking normally. Her pee is normal in color and texture no blood in the urine. I have read that sometimes when in heat the mucus plug dissolves. Is this what the discharge could be or is this a sign of UTI?
