Cat Dog Hybrid Illusion

When you look at the image below,At normal screen viewing distance you should see the face of the Cat. Now squint your eyes or take a few steps back from the image. Does a Dog pop into view?

It is interesting to note that without the provided original images for comparison, the hybrid could be imagined as a real image. The features of each animal blend together; the nose of the dog becomes a shaded patch on the face of the cat. Although there is a successful and definite switch that occurs with altered distance, the hybrid itself appears as if it is a new animal all together.
