Births in Europe and Texas have occurred from March to August. The gestation period seems normally to be 86-93 days. The number of young per litter ranges from one to five but is commonly two. The young weigh about 140-70 grams each at birth, open their eyes after 12 days, take some solid food at 10.5 weeks of age, and nurse for 5 months. The coat is initially black in the patterned areas, and full adult coloration is attained at about 6 months.
Many captives are gentle and playful and like to be petted by their custodians.
The main problem is loss of forest habitat to agriculture. The species also has been excessively hunted in some areas for its beautiful pelt. It may already have disappeared from Hainan, and in Taiwan it is restricted to the wildest and most inaccessible parts of the central mountain range.
