Hi I am new to this forum and I wonder if anyone can help me? I have a two year old, long haired, syrian hamster who, after the recent heatwave, began scratching and chewing at himself. On further investigation I saw that his skin was scaly with dandruff. He also has a black, crusty patch on each side of his hip. I purchased some Ivermectin drops (0.1% and £16!) and applied it to his back 5 days ago. I'll repeat it again as does not seem to have helped. Does anyone know how to treat this without going to the vets? Thanks!
