[Petite]

I currently have a hybrid dwarf, although have had winter whites in the past. I would say any odour from them is similar, but I use Kaytee Clean and Cosy bedding which helps to minimize it. Until shortly before Christmas, I also had my first robo (female) and there hardly ever seemed to be any odour from her at all, and certainly less than a hybrid dwarf. (Sadly, she got very sick and died.)

I would recommend going for a robo is that's what you want, although you will need to be prepared for the fact that you may never be able to stroke her or pick her up as they are rather more timid than other hamsters - and usually also too fast to pick up - our Holly moved like lightning! We eventually reached the stage where she would take a sunflower seed from my fingers, but I was never able to stroke her, although that wouldn't stop me from having another.

I have similar problems to you re neurodivergence, and didn't have a problem re odour.
