My immediate thought was also fashion designers. There are so many good names to choose from - somehow they all seem perfect for cats:

Vera Wang - I like the name Vera for a cat!
Carolina Herrara
Liz Claiborne
Donna Karan
Nicole Miller
Anne Klein
Coco Chanel
Nina Ricci
Oleg Cassini
Geoffrey Beene
Cole Haan
Oscar de la Renta
Calvin Klein
Ralph Lauren
Perry Ellis - good cat name!
Donatella Versace
Georgio Armani
Atienne Aigner - sounds more like a poodle!
Karl Lagerfield
Hugo Boss
Pierre Balmain
Pierre Cardin
Christian Dior
Yves Saint Laurent
Louis Vuitton
Alfred Sung

How about Isaac Magrahi???

PERFECT: Yohji Yamamoto and Kansai Yamamoto

I'm sure there are hundreds more!!
