From what I've been told, they vent a anal gland as a defence mechanism, now from what I know (couldn't get the smell off my hands for about 1 hour, no matter how much I washed) Its like they rolled through something dead :shock: After awhile (a few washes) its not unplesent ,just very musky.
Sounds strange but works to cut most odors from anal glands spraying or venting....Soak your hands in tomato juice... just rub in and then rinse.
Some people in my area keep them outside in bird averys. But then the climate is ideal around here for them.
