Hi, I just found this wonderful form online today. I have two boy guinea pigs. Both are three and half years old, I look after them very well and I love them very much. Recently, I noticed one day, I can see one guinea pig's willy from behind. I check from front, it looks normal. And my piggy eat, behavior normal. I wonder if this because he is getting older, his willy starts to change or he has other healthy issue? I would like to attach a photo here, but don't know how to do this. I find there is a Insert image on top, click it, but i can't copy and paste a image there. Could someone tell me how to load a picture? Thank you very much for your help! zhumama{means piggy mum in Chinese)
