Open Question: Help! I think my cats have a foot fetish!?

[feedcrawler]

I have to cats one is a year old and the other is 9 months. The first I got a six weeks old and the other I got about 3 months ago. The 2nd one seems to have a thing for sniffing feet and shoes. It does matter who it is or what their feet smell like he wants to smell then and their shoes. He has done this since we got him and now my older one is doing it. Why do they do this? Why do they smell the stinky ones even longer?
