This being my first rat neuter, I'm not sure what th expect in some ways. My other neuter boys have no "baggage" left but I assume that's because they were young tiny when neutered. was surprised yesterday to get wolfie back with two harble shaped skin hanging down in back. Looks just like goolies but there's definitely nothing in there. Incision was made just below his penis, it appears. He's started licking at it a lot today. I've been finding some blood staining here and there in his cage, isn't dark, like its diluted with other clear drainage. Is this normal? Should I worry about his licking attempts? Will that excess skin retract or stay empty or fill with drainage and how do I know if it feels "normal"?
