You could just make the ears yourself. It's what I did. They're really actually quite simple, as long as you have at least a basic grounding in sewing. I'm probably not the person to ask for instructions, but I found a pretty good (if unspecific) tutorial on DeviantART.

http://SedatedArtist.deviantart.com/art/How-to-Make-Cat-Ears-Revised-64515635By adapting this basic outline, I've created cat ears, fox ears, tiger ears, and even rabbit ears. And they were cool, floppy bunny ears with long fur on them, so no worries, Arbutus. I share your pain. They were still the cliche white colour, but I wasn't making them for me, they were a commission for a friend. Even then, I still made them an off-white, creamy colour, and she loved them all the more for it.
I hope this has helped a little!
