Not sure what to do. Whilst cleaning out my robo squeak, I've noticed quite a large patch of her back with her fur missing. From what I can see it hasn't cut her flesh. She is a lot more skittish that normal, however she has never really wanted human interaction as it freaks her out, but she always let me put my hand in her cage to feed her and sometimes eat off it. Anyway when I go near her now she nearly jumps a mile ... Not sure what to do. Do hamsters usually lose fur?

Can you tell if she's scratching at all? Also, is she elderly? Is this the first time you've noticed it?

If it's not mites or age related fur loss you might want to take her to an exotic vet. They would be able to tell if they want to rule out mites or not? Usually there is continual scratching tho with mites.

It could be several different things but I'd only be guessing where a vet would be able to let you know I would think quickly. But definitely make sure it is an exotic vet if you take her in for an exam. Sorry this is happening.

She is not paying attention to her loss of fur and not scratching at all, does that make a difference?

Is there anything in her cage which could be rubbing it off (sometimes they try and squeeze under small gaps - like under a wheel say? I also wondered how old she was.

If she's not scratching in my opinion anyways your probably looking at something else besides mites causing the fur loss.

Some of the things it could be is hormonal, age (doesn't sound like age tho), internal tumor, Cushings, these are things that like I was saying only a vet would know for sure.

It's good that it doesn't seem to be causing her any discomfort at the moment. I'd still take her in so you would know what your dealing with.

You don't have to pay for expensive tests if the vet recommends testing, but just for peace of mind they might be able to tell you during the initial exam what they think it is.
