Tubby had all black whiskers except one white one. Just the opposite of Dylan and PB & Stubby! I was going to post a pic but Imagestation isn't letting me in for some reason - drat! This whisker would fall out now and then, but would always grow back....in the same place.

Peanut and Cracker Jack both have white whiskers. I haven't noticed any black ones on Peanut, but now I'll have to look since she does have some black hair in her....

So to answer the question, yes, my kitties follow suit.
