I wouldn't trust that "they're not smart" thing. Not being hyper active doesn't mean they're not smart, which is often what people seem to think. And Himalayan is just a colourpoint Persian, so hard to imagine that there would be major differences but I'm not an expert. My step-dad had a blue...
Red/brown splotches on her back are telling you her colour is (brown) classic tortie tabby. Domestic Shorthair (unless she's registered pedigree cat, in which case you probably wouldn't be asking).
^I thought only shaded pattern was recognized in Burmillas? But then again I'm located in the "rest of the world" and not USA, and our main registry may have different colours. I've only seen shaded Burmillas in shows, never any other patterns.
I have a sign on my door which says "The more I meet people, the more I like my cat".
And to OP's question, yes that is ripping people off. Then again the people buying the kittens haven't done their research and seem to be stupid if they think they can get purebred un-neutered kittens for that...
She's a tortie tabby with white. Can't see the exact tabby pattern 'cause her tail is blocking the view, but a mackerel if she has stripes, spotted if she has spots and classic if she has big thick swirls on her sides. Without registration & pedigree, she's a domestic longhair. Very pretty.
