Kittens Barbie and Ken want a dreamhouse!

Barbie and Ken! Two super fun all black kittens.
They are spayed and neutered and already vaccinated with FVRCP.
They are litter box trained as well.
They are about 5-6 months old.
Barbie (female): she's small and sassy, has a strong purr and a lot to say.
She's the playful one out of the pair.
Ken (male): he's a behemoth! Kind of a dunce but we love him anyway and his little sis takes care of him.
A little timid with new people/new environments but warms up really fast.
We would really love to get these two a new home together.
Ken would be fine on his own but Barbie needs a buddy to keep her busy.
Rehoming fee of $100 total if they can go together! donated directly to a rescue that has been helpful with resources via their online link (they are a 501c3 so tax deductible too!) Kittens are currently in westwood but happy to drive them for a meet and greet within a few hours of Los Angeles!
