If it were me, I’d go the route of staying with an astronomical theme. Luna: very nice name and a very cute cat … reminds me completely of my older cat when she was a little thing. Same black hair and yellow-green eyes.
I think a “lunar” counterpart would be a fitting match. Luna & Callisto sounds perfect. 
There was also a goddess from Greek mythology, Soteira, another name for Athene (daughter of Zeus). I always thought it a beautiful name … perfect for a cat.

Name th Black & White Kitty HOLSTEIN (LINK)–aka Cow-Cat, for short.
Tell the truth: the pattern is the same, ain’t it? 
If you want to continue with the “star/space” theme, you could call her Eclipse!
Bella was definitely what leaped into my mind.
What a fun-looking kitty.
Our space-theme named cat is Cosmo, in honor of Carl Sagan actually. She’s also black and white, not super-cuddly, and was the tiniest cat in the world when we got her.
So, Cosmo!
Speaking of cows and Oreos, there is a type of cow at a farm near me that’s new to me: looking at it from the side, it’s a vertical Oreo! Black head and front and front legs, black butt and tail and back legs, white wide stripe all the way around the belly!
Bye Jack!
My daughter and I have decided that “Angel” is not a good fit, but “Demonic Hell Beast” doesn’t exactly roll off the tongue, either. She was so sweet and cute and endearing when I first met her, but as soon as I got her home one of her other personalities took over, apparently, and she has done nothing but hiss and snarl and growl. At first she was only doing it to Luna, but now she’s taken issue with the fact that I’ve been cuddling and comforting Luna, so she’s hissing and growling at me.
She hasn’t actually attacked the other cat or me, which is why I’m willing to give her a few more days to settle down and learn to play nice. But I cautioned my daughter not to get too attached because if she can’t learn to get along with Luna-brat then I’m going to have to find her another home - one with no other cats. She’s using the litter box and eating and drinking and playing and everything else, but whenever Luna gets anywhere near her she goes all hostile. And poor Luna is so dumb and clueless, she just wants to play.
She’s sweet as pie to my daughter, though. I’m starting to think she may be one of those one-person cats that acts like a total fiend to everyone else.
Moo-cow might be a good name. She does kind of look like a cow. An evil, hissing, snake-eyed, conniving demon of a cow. I still think Bella would work, too. She’s kind of psychotic like Bellatrix LeStrange.
black and white cat, companion to “luna” (moon)? Eclipse, of course.
Wicca or Wicked comes to mind since my other names don’t seem to work.
Spike?
Heh uhm. Thanks?
I always figured if I got a cat I’d name him Schrödinger, or maybe not, it’s 50/50.
My first and last cats (my girlfriend’s idea) looked like little lions.
So one was named Dreyfus Fund which has a lion logo.
And the other was Merrill Lynch Pierce Fenner and Smith to follow the theme.
Since cats don’t really need names, the length of the name didn’t matter.
I suggest “Pud” (rhymes with ‘would’)
That was the name of our cat when I was a kid, and it has a certain English down-by-the-docks roughness about it…
For the kitty cat who evades the police, the perfect name is Sing Sing.

I think you should name her Butler. That way if anything ever goes wrong, you can just say that Butler did it.
I was pushing for Bella, but my daughter declared that her name is Oreo. So Oreo it is. Although I kind of like Sing Sing, now.
She and Luna finally made up, and can usually be found cuddled together on my fuzzy blanket on the couch, sleeping, unless they’re awake, in which case they can be found hurtling around the house ambushing each other. I’ve got new pictures, but I haven’t downloaded them off my camera yet.
