Naturally, Shumshu is using his nose all the time. When I come home from the supermarket, he has to try and find out what I have bought. And I let him smell things, to learn what the different things are (or at least smell like). A couple of weeks ago he was on my desk when I was printing something out. I had a great laugh! You know that the paper comes out a little by little, and not evenly. And every time it moved, Shumshu jumped backward. Now he knows what is going on, but he has to smell this think making noise and coming out of an opening in this thing on the table.
