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 Ps. Sorry if this is in the wrong section, i am new to this site.
