How to tell if she's a purebred Ragdoll?

I was recently asked to find a home for a cat. Supposedly, her original owners "paid good money" for her, and they said she's a purebred, "papered" Ragdoll. But her papers have been lost . She certainly has very blue eyes, and has the soft longhaired coat and snowshoe-type markings, but she's not especially docile or "floppy". She hates being held, and kicks and jumps away. And she started a fight with Fiona when introductions were attempted (Fiona IS very docile and never starts anything or fights back). And one thing said that Ragdolls always have white chins, and her chin is tan. But of course not all purebreds completely match the breed ideal. Anyway, I don't want to market her as a purebred if she isn't. I'll try to get some pictures up soon. Is there any way to know for sure?

Hope that works! I took about 10 pictures and that's the only one that wasn't blurred. And it's on my cell phone so it's not the greatest. She's fat!

Are Ragdolls supposed to be splotchy? All the cats in the pics I see online don't seem to be splotchy. But then I suppose most pics are of show cats, not pet-quality. This isn't the best picture, but it shows her splotchiness.

I'm not in contact with the original owners. They used to live here but moved. The person who had her before got her from the original owner's mother. . .etc. Poor kitty has been around a few times, and she's only about 2-3. I would like to find the breeder, but, to be honest, anybody who would sell a kitten to those people is probably not responsible enough to take back their cats. The original owners have a bad track record. . .when they lived here, they went through 3 dogs and who-knows-how-many cats, and they were only here a couple years. I might try to dig around some more, but chances are slim. I might have the vet check for a microchip. . .I hear some breeders 'chip the cats in their name before selling them.

I woudn't advertise her as definitely a purebred. . .I'd just tell the potential adopters what I know--that the original owners said she was purebred but I don't know for sure. I wouldn't want them to have nurealistic expectations about her personality, anyway. And since she's spayed (and de-clawed ), it doesn't really matter, I guess.

Besides, she might stay in the family. My mom loves her and wants to keep her (but my dad probably wouldn't agree to it--this would make 5 cats for them). And my grandma recently lost her kitty to mouth cancer, and I think this one would be good (except she thinks cats should always be allowed outside, and I don't know if we could convince her that a de-clawed cat shouldn't). Anyway, I'm sure I can find her a home.

Oh, she's fine. She's living in a bedroom at my mom's house and seems perfectly happy. My brother is looking into his apartment's requirements for having a cat. But we've all been busy with work and school (my brother is a student) so nothing has really been done.
