I have this listed in a few places as one of the things about me, and it's true! I just found my little bottle of whiskers yesterday. It had been packed away for the last three years, while we relocated. I found it in a shoe box while clearing the space in the laundry room for my seeds.
All the whiskers I ever found, from every cat I've had as an adult -here in a little medicine jar. (Updated as needed) As of 12/30/09 the collection is up to 399.
