Hello! I'm sorry to hear about Pepper being so itchy! There are two main things I think about when I see itchy hamsters- skin mites and ringworm. It would be helpful to know if this started happening after contact with a new hamster, as it is often a contagious problem. I would recommend taking her in to see a vet that is experienced with hamsters. They can perform a skin scraping to check for mites and take a sample of hair to check for ringworm. Mites are treated with an anti-parasitic medication, while ringworm is treated with an anti-fungal medication. Once the cause is treated, her skin will be much more comfortable and she will stop scratching so much. As a note, ringworm can spread from animals to humans, but is generally easily treated in people. If you have any skin rashes, check with your MD! I hope you find this helpful! Best of luck to you and Pepper! :)
