This is a Banded Civet. There are many species of Civets. They're called civet cats but they are not cats, they're their own thing entirely.
The wife and I saw two of this species on this night drive. These seem larger than most civets and appear to stay mainly on the ground.
The other asian civet species on my site seem to spend a lot of time in trees.
