Hey everyone -- Over the holidays, I noticed that the penis of one of my rats (Scotch) was extended completely and would not retract -- he was constantly licking it, and squeeling every once in awhile. It seemed quite red and irritated. Too bad it was Christmas day and there were no vets around! A few hours later, there was a yellowish mass protruding from the end. I tried gently squeezing it out, but it would not bulge, and it seemed to be causing him a lot of pain. We eventually managed to get it out by placing him in a warm bath, massaging the area and squeezing a bit more -- he struggled a bit, and this seemed to help move it out. The object was about half the size of a small marble and hard -- what a terrible ordeal for him! I tried researching it on google, and I found some articles on kidney stones and 'penis plugs', but I'm still not sure. Has anyone had something similar happen to their rats? This is definitely something new for me!
