Wow, that's a beauty! Looks like a Britannica/Lowlander, correct? How old is she, 2-3 years?
I have an Eich/British Shorthair , 8 years old, and he looks a bit like this one, but with a black nose
I must admit, I dont know much about cats, this is my first cat, and I rescued her as the local pound was going to destroy her, and she was pregnant also, and by law, that hat to terminate the kittens and neuter her, and for a couple of weeks she had a neck cone on, cause she kept trying to bite her stitches. There are some funny stories about those few weeks. Anyway, I just fell in love with her and she has changed my life.
