Greetings. We have had our Syrian hamster for almost a month now. My son noticed last night that Comets nads looked more swollen than normal. They had a blue tint on one side. Today that area has turned more black and it looks like it is spreading. Does anyone know what this could mean or have you seen this before? It’s rapidly spreading. We have a girl hamster as well and I was under the impression that Comet(boy)was aroused. He goes crazy if she’s near(we do keep them separated but at times we will bring them out of their cages at the same time and he starts going nuts sniffing around trying to find her. I’m inserting a picture if anyone can assist.
