Well, I can't help with the body shape of the P4 cat, but you can download a pure black texture at:

Jackie's Stuff for Poser

I do, however, have some eyeball props in Free Stuff, which replace the cat's wretched, non-posable default eyes. You can see a few test renders here.

(AnthroEyes should be updated to version 3.0 by March.)

And the expression morphs I included in my Tobi 2.0 freebie should also work with the cat. The morph deltas can be transfered to the cat's CR2 with Morph Manager.

And my Bushy Tail 2.0 freebie can be used in place of the cat's tail. A black texture is included in the package.
