I finally tracked down a couple of Catwalk Kitties, the presumably unsuccessful cat-model doll release from Lanard.

These pictures are of Toffee and Anika (not in stock clothes), who are two of the ‘Models’ in the series. The others are Purrl, Sushi, Sienna and Minx. The other half of the series are the ‘Behind the Scenes’ dolls: Callie the model of the year, Topaz the make-up artist, Jet the fashion Photographer and Chase the modeling agent. These last ones are supposedly harder to find. There are also petite versions of many of the dolls.
Their bodies are a bit like Barbie or Bratz, as they’re not very articulated – their heads, hips etc twist but only their knees bend. Their feet come off like Brats feet, but aren’t switchable due to the plastic colour being different on each doll.
According to the response to my pestering email to Big W, they’re definitely discontinued. They’re also MIA on the Lanard official website. Though the ‘harder to find’ ones have popped up on Amazon.com and many are still gathering dust in a few places around Australia, like Big W and Toy Kingdom and a couple of other shops. They can also be found in a few countries around Europe, but I’m not aware of the details.
I wonder if they’ll the next Peteena. It’s a pity they’re not making any more.
