Pretty babies! I think they will be short or medium domestic short haired kitties but I am no expert........The one with the tiger stripes markings could pass as a Maine Coon, maybe; best thing to do is look at the parents and go from there.....Cat lovers will pay for what they want, if in fact your friend wants to sell these lovely babies at all.......I bought a Himalayan kitten about a year ago simply for the looks and purr---sonality even though he wasn't registered and can't be..........Stella is a cute name, by the way, best of luck and give them some hugs & kisses for me.
