My hamster has matted patches! Please Help!!?

Are the wet patches further back on his body? if so they are scent glands and nothing to worry about. Male hamsters often smell stronger than a female. This is due to body odor from a scent gland called hip spots or flank glands. Females have these glands, too, but they are smaller than in males. When the male licks the glands, the musky odor is produced. Syrian hamsters have two glands while dwarf hamsters only have one. Some hamsters just tend to lick these glands more which will do him no harm at all. It will be more noticeable in long haired hamsters. I hope this has been of help and good luck.
