A clean living environment plays a large role in keeping your ferret healthy. This includes cleaning the cage often and changing the litter about once a day. Of course a proper diet and preventative care is also highly recommended.
As for ferret skin care, it is important not to bathe your furry friend too often as this strips natural oils and can dry out their skin and natural defenses. Also, when you bathe your ferret you’ll want to do it correctly. This involves using specialty ferret shampoos and products. Never use human products on your ferret!
