I have a half Siamese/half only God knows what that I got from the SPCA. Her face looks exactly like your Siamese. But her body is partly white with Siamese colors interspersed. She has many of the Siamese traits such as following my son around WHEREVER he goes. And her fur is incredibly soft. Her only bad habit is sleeping at the top of stairs (ANY STAIRS) and refusing to move so you can get past her.
Just like with your son, Sam follows or leads me everywhere, too. That's one of things that makes her dog-like to me.
She'd get out of your way if she'd been kicked out of the way a few times, something which I'm glad you haven't done. Be thankful you have to step over her.
