Such beauties and the mom is gorgeous. It is hard to tell from these pics if they have points, one looked like it in the early pic. And the body looks too dark too early mostly but some burmese are like that as others said. They def have some tabby stripes.
They're really confusing, lol. If they were pointed, they'd have blue eyes. But they clearly have something going on with the marbling and shade differences. Maybe that's what ghost stripes look like if they're classic tabby under the solid color? It would be cool if a genetic expert took an interest and did a few tests, but we'll probably never know what's up.
I know they have ghost markings but there markings are the grey, the cream is their base color. They are still a beigy cream. Just never seen their coloring and I myself fostered a blue kitten with ghost markings but she was nothing like them lol. We've had thousands of kittens in care and none were ever like this. I mean as a young kittens they looked like cream gingers. There was this cat at the golf course area to that they believe is related so a colorpoint could be possible. Maybe a blue sepia?
