My hamster has fur loss and red scabs. What's wrong and how to treat?

My hamster is around 5 months old and has recently developed an area of fur loss with a red scab underneath it along with small patches. I can’t afford a vet check up and it seems to be getting worse. There’s nothing in my cage that would’ve done this ( I have a completely safe wheel, etc) and I’m really worried. What condition do you think she has and how can I treat it?

Thank you for using Petco Pet Education Center, formerly Petcoach! It is a little difficult to see in the photo, but there is what appears to be a small area of scabbing and hairloss, both of which are patchy on the hip. This can be caused by a skin infection, certain cancers, fungal infections, or skin mites which are very common in hamsters. These mites live within the hair follicles rather than cage surfaces, so cleaning the cage will not get rid of any of the possible causes. Mochi should be seen by a vet who can perform some quick tests on this area of skin to determine the underlying cause and start her on the appropriate treatment. In the meantime, to keep her more comfortable, you can gently trim her nails to keep her from traumatizing herself as she scratches. I hope this helps!

Thanks for reaching out about Pom and including a photo. The picture shows a dermatitis with possible causes mites, bacteria, fungus (ringworm), endocrine problems or trauma. Most of these are also itchy so a portion of the lesion can be self-induced due to scratching. A veterinary visit is recommended to assess and provide a treatment plan. Good luck.
