My take on it would be
fur: Russian blue
eye: Onyx (myst, big or small) And Wow! we now have a black eye on the grid. So exciting.
shade: ? glitter? I think Russian Blues really look best with flair on them, but that's a personal preference.
tail: oh go for Dreamy.... if not, well, frisky or sassy would work too
ear: foxie
whisker: dusky (plush)
No, I don't have such a cat but I wish I did.
You haven't said who your Idol is, but I suppose we should let that be private unless you want to share.
