That looks like what one of my cats looked like as a baby.
Siamese color changes over time so all of them have the same when young but as they get older some areas get darker and that's different (I read somewhere it's the areas that are colder)
One of my cats sits like this all the time because her back legs are differently perfect than other cats.
We can argue the ethics and wisdom of dating a cat, but not her beauty.
My daughter poses for me too
