I will do so, thank you so much. My son is really good at picking them up so I will get him to do so tomorrow sometime so I can take a pic.
Hello there,
I do not vet hamsters often enough to answer your question. However, I will ask one of my colleagues, to try to help you. Could you please paste a couple of good, well lighted photos of the belly areas of your hamsters for us? This will expedite evaluation. And also please post again as a new question with the photos.
It might also help if you post to the exotic forum in community.
