Male vs female dwarf hamsters - smell

[Kyrkogrimr]

Not a problem as much as curiosity, but I've noticed that Carbon smells more than Cadmium did and I was wondering if this is a male thing, a new home thing or a Carbon thing. Or a mixture of the three I suppose.

It doesn't smell bad, it reminds me of wood shavings and I've noticed it most around his house/nest. I'm not sure if he's peeing in his nest (Cadmium was always a nest-pee-er) but I know he uses the sand bath for that.

So what's your experience been? Have your boys been smellier or girls?
