[SKB_Hamsters]

Hamsters do groom a lot so it can be hard to say if the grooming is excessive without seeing your hamster in person. Can you see her skin my any chance - Does it look red/inflamed?

Mites on hamsters you won’t be able to see unless under a microscope - the way determining if mites are causing the scratching is for vets to do a skin scrape.

I know you said you don’t use cedar or pine - but what other bedding do you use in the cage as it may be an allergic reaction to another substrate? Or even a food allergy which is harder to identify.

How long have you had her for to? As some hamsters when stressed will groom excessively.

If the scratching still seems to be excessive it might be good to get her to an exotic specialist vet - who will be able to determine if any underlying issues are causing the scratching.
