Maybe she is a tortie point? The tortie point mama that I have in my care has a couple of tan splotches on her back.
The faint marks on her body wouldn't be visible at birth on a tortie-point anymore than the coloured ears, face and so on are. I'm guessing this is the last of the kittens above, just coming in with blue on her ears, but she could well turn out to be seal.Thank you both, and with momma being a chocolate Tortie point and blotting on her body both can be true, just have to wait and see I guessit is a Female as far as I can tell and it is a point. My daughter is keeping her so we shall watch her develop!
