Thanks Mark.
I love cats, both wild and domestic, they're just so intelligent and resourceful.
The Contax G adaptor arrived yesterday afternoon, I immediately dropped what I was doing and shot a few pics.
Attaching the lens to the Fotodiox adaptor seems a little fiddly at times- you need to make sure that the lens clicks into place fully, requires a little extra twisting force to achieve this.
Focus is then easy using the adaptor's ring.
Here are some images, these are Jpegs straight off the camera with no post processing at all.
All shot at f2.8
I think you're correct about the Contax 90mm G. From the little I've seen it's absolutely stunning on the X-Pro 1.
