The most striking difference between Ellie and Louie is their coats. Louie is blessed with a thick semi-long hair coat. It grows thick around his middle, tail and neck. This we think leads to different behaviors. Somali's also have what is called "ticking" in their coats. This gives the effect of darker fur in places. In Louies' case he has a thick dark red line down the middle of his back and tail. This grows more profound as he grows older.
Consequently Louie is not so worried by the cold and never attempts to kidnap the duvet. He's also more likely to spend hours on end outside while Ellie will watch from the window.
