Good name! One of my two cats is named Atilla. The other is Tobermory.
It has been my experience that rabbits and cats generally don’t get along. My rabbits have usually beaten the snot out of my cats until they learned to leave the rabbit in peace.
All I know is that if I could, I’d name her MINE! She’s perfect!
You may not want to go with the Bunny name, as you HAVE a bunny already.
Unless the bunny’s name is Kitty. In which case, it’s a no-brainer.
That is awesome. I’ve known rabbit owners who were very reluctant to let their pet graze on the back lawn in case a neighbor’s cat came after it. I’m glad to hear your critters have things under control. 
I had a cat named Martha. And a cat named Naomi. Now I have a cat named Kitty (he climbed in my son’s bedroom window and went to sleep in a chair. . .and has been the feline overlord for 10 years) We did not know if he lived somewhere and was just visiting, so we just called him Kitty.
Mookie
I like Marbles!
Sure looks like a Cookie to me!
PandaKid says Hazel or Ruby.
MrPanda says She-Ra
I’m partial to Tango.
She is SO CUTE ZOMG SRSLY!!!
I’m feeling Kit Kit.
My mom has a cat named Fido.
As for the kitten in question, some of the names I like are:
Gertie
Greta
Lucy
Kissy Missy Fluffenstuff
Yolanda (Yoli)
Beezus
I believe there are three votes for “Marble”.
Sweet little Marbie.
MAR-ble, stop that this instant!
MARRR-BLLLLE, dinner!
Has a nice ring to it.
Marbles is cute, but I agree that she looks like a cat who needs a person name. I like Frances, maybe Franny for short?
Tabitha
Thus calling the pussy Pussy?
She is the prettiest little kitty…what about Bella?
If you want an iconic Aussie name, how about Gough?
How about Tim Tam? (Kit Kat being too obvious).
Petunia or Tulip came to me when I saw her picture.
My next kitten is more than likely going to be “Rover”
Or Spot
Of course he/she will hold that against me it’s entire life.
Oh well.
I have a question: how come she’s so cute? I mean, seriously.
So cute!
How come?
HOW COME SO CUTE?!?!?!
