I kinda get what you're on to, though I can't share it much with you although in it's essence it's a pretty hot idea and I plan to try it out at some point in an LD. In fact I heard of this idea multiple times from others. I mean.. cat girls are hot to a certain extent.

It probably evolved from me watching the musical Cats when I was 12... half naked hot girls in skin-tight cat costumes?
WESTERN CULTURE WHAT HAVE YOU DONE

No but seriously.. I'd never want to be killed in a dream. I'd accept this idea as far as the outer appearance is concerned but not more than that. Also it should be min. 80% human.
