Picture of Clouded Leopard (neofelis nebulosa)

Proportional to their body size, Clouded Leopards have the largest teeth in the cat family. Cloudies are also great tree climbers, although not enough studies have been done yet to really know just how much time they tend to spend off the ground.

In an amazing discovery announced earlier this year, the Clouded Leopards of Borneo were determined to be an entirely separate species of cat (Neofelis diardi). They are genetically nearly as different from the mainland Clouded Leopards as Lions are from Tigers.
