Hi Steve I am not certain about or whether it is a race, could be "Norwegische Waldkatze" = Norwegian forest cat. They wanted to kill him 3 years ago, because he was fighting with all the other cats, I got him from the doctor and do not know more about his history.
Yes, Leo Leu Lowenzahn is "a bit larger", in fact he is huge, around 6 Kilos, nearly two times that of my former male cat. That's why he has 3 times "lion" in his name, but "Lowenzahn" = "Lions tooth" is also a very common yellow wildflower ( you can make salad with it) you find everywhere. He received the last part of his name, because, when he bytes you, you know it for sure! He is like a dog following me for walks... Markus >> Is there a name for these orange and white cats?
