This is the Iriomote Wild Cat Secret figure. This model exists in different poses by Kaiyodo but this particular one was released as a secret item in one of the Choco Q series. It is because it is a secret figure that images of it were not shown on the leaflet that came with it or on other documents. This model comes in three colour shades, the dark one (above), a middle colour and a lighter colour shade.
Each series of choco q capsule animals always had a secret figure included. Hopefully someone else will have more info and weblinks for you. Secret animals are a little rarer than the general range but they can still be found online so it is not impossible. If you want very rare then try the Vanishing Wild adult Gemsbok by Safari Ltd now that is a goldmine! :-)
