I love Catty Noir! She is even more unusual than the others with her long cat tail and pussy-cat ears and nose, and I believe this is the first edition of her? It says on the box she is a pop star - hence the silver glitter boots! Cat in Boots :)
I'm an adult collector and these Monster High Dolls are just brilliant with their scary uniqueness, haute couture clothing, wildly colourful hair and imaginative styling. Young children must be careful not to break them as they are a little delicate condsidering their ball-jointed limbs.
I would say that Catty Noir will be one of the best collectable MH dolls, so if I were you I wouldn't miss out on her. (I bought mine for £20 from the Tesco's web site; shopping around in supermarkets and online is worth the hassle for getting the best deals, especially with MH dolls. At time of writing this review, some of the MH dolls, '13 Wishes', are at VERY low prices on Amazon!).
One more thing...I have to say, she reminds me of the elegant, cat-asmatic (charasmatic) Grace Jones ;)
