Hello again. Thank You for all the advise. Today he was running on a big blanket and started to wash himself a lot again and after that there was a wet spot of fur and same kind of red spot on the other side too so I assume it has to be the scent glans. He looks fine just washes himself a lot- and he's back looks too dirty to be natural grease... tried to brush the hair with soft toothbrush- didn't make any change and he didn't let me to do it much. Well, I'll just give him time and we will see if he will eventually get it clean. Do you think giving him a bath in few days (if it's still greasy) would be a silly idea?
P.S. Also removed the bedding fluff.
Thank You everybody.
I am a Hamster breeder and I see this behavior as they begin their heat cycles. The "grease" could just be from the new glands working. They take that oil and put it all over their body and on things in their cages that they claim. Some hamsters have more "oils" being released then others and need more sand baths then others. This is normal.
Never bathe a hamster, as they are never meant to be wet! They are desert animals that live in dry grassy steppes or in sandy desert areas. Never wet a hamster. To bathe, they roll in sand. I suggest buying Chinchilla SAND (not DUST) or some play sand from Toys R Us for them to bathe in. The Play sand needs to be washed before hand and dried out naturally before you can allow your hamsters to roll in - but the Chinchilla sand bath is already cleaned and ready to go (Animal safe). Do this sparingly or when necessary as some hamsters get allergies or the sand in their lungs if used too often.
I think your hamster will grow out of this "dirty/greasy" stage as he matures. His hormones are just going crazy - kind of like puberty eh?
