Some notable species include:
The African Civet
Civettictis civetta

Spotted Linsang
Prionodon pardicolor

Owston's Palm Civet
Chrotogale owstoni

Small Spotted Genet
Genetta genetta

[Also, notice the rather massive looking spider next to his tail>.<]
Plus many other similarly stunning critters.
They are typically shy and elusive and whilst classed in order Carnivora, many species are not adverse to supplementing their diet with fruits and berries. They are also typically strong smelling and some species are raised for their musk, which is used in perfume.
The endangered and vulnerable members of the Viverridae family are usually so due to habitat loss.
A few, such as the Small spotted genet, have been succesfully kept as pets.
Please feel free to add more information [I tried to keep it short and sweet for the first post] and pictures^^.
