I came to this post rather belatedly and thought, in the name of science, that I should conduct a similar experiment on my Marsha to check if she indeed has Frito paws herself. That was the first thing I did upon coming home last night...initially I couldn't smell much, because I was holding her paw about a half inch away from my nose. It wasn't until I had my nose buried in one of her spread-out paws that I finally caught a whiff of Fritos! I had a hard time explaining to my Mom what I was laughing so hard about! She thought I was going mental!
