I have two kittens myself and they love each other (they aren't littermates at all). But see by your description of Molly I'd say her and my Pearl are twins seperated at birth. LOL.
Pearl is lilac point and has long hair but that's the result of her mommy being bred with a Persian. I can't wait to see pictures of your newest addition.
Our crew, (Mom, Dad and the 3 kits) always amuse each other. They even annoy my hubby at the same time, begging for treats! They know he is the keeper of the treat bag. LOL
