I don't think there's any big fansites dedicated for this doll line. At least I've not found any myself.
I think there were four releases:
1. 6 models (Purrl, Sienna, Toffee, Anika, Minx & Sushi) with a suitcase, pet cat & carrying bag for the pet, plus a handbag with some make up, cell phone and other small accessories.
2. Same six models, but without a suitcase and pet carrying bag. Also at least Purrl, Toffee and Anika had different, simpler clothes.
3. 4 dolls with pet cats and handbags with usual bag accessories were released with playsets. These were:
- Chase, the modeling agent, who came with a computer desk, a chair, a lamp, a potted plant and small accessories to put on her table (a flower vase, a clock and such). There was also a cardboard calendar with markings. If you click the mouse (that looks like a mouse), the computer lights up and Chase's "voice" says something from a voice box hidden inside the desk (I hate toys that talk, so I took batteries off from mine.)
- Topaz, the beautician/hairdresser/make-up artist, came with a hairdresser's table, a chair and tons of little beauty products and beautucian equipments. This time, if you pressed the cap of a bottle on the table, you'd get the voiced lines spoken.
- Jet, the photographer, had all kinds of photographing equipments, but I'm not good enough in English to name them all. When pressed, her camera actually flashed and made a click, followed by a voiced line.
- Callie, a model, came with a huge runway set, that lights up and plays some music, I think (haven't tried, since I don't like noisy toys and removed batteries). There's a stage with a catwalk, a stairway leading to a second floor above the stage and some equipment for the changing room (a coatrack with 2 coathangers, a table with refreshments and flower vase and such). What I like about this playset is, you can combine it with Chase's office and Topaz's hairdresser's table. They even put a picture of Chase's desk on the second floor, and Topaz's behind the stage, as if to hint, hey you can put these here, to combine the whole Catwalk Kitties Modeling Agency (except poor Jet, whose photo studio appers to be somewhere else. Maybe in the basement?).
The last line was the Petites, or Minis, which were smaller. There was Anika, Chase, Purrl and Toffee. They came with a pet cat, a handbag and little accessories, and, if I remember correctly, a swimsuit (that I thought looked more like underwear). Two of the minis, Anika and Toffee, had another release, with a scooter and a different outfit.
I'm not sure which line of the 6 models was first, the one with suitcases or the one without them. But I'm pretty sure the playsets were a later release, and that the minis were the last.
I haven't got all of the dolls and some of the ones I have I've gotten loose, but I got a few of them with all accessories, so if there's a particular doll you'd want information about, I'd be glad to help.
