Worry not a jot. You'll find whiskers occasionally, as well as bits of their claws too - like the way a snake sheds their skin and you see the outline shape - you'll find bits of claws around too.
I am a bad mother - when I find one of Molly's whiskers, I go show her it, let her smell it then I gentle 'prod' her in the belly with the 'root' end (simple things amuse simple minds... I know, I know
)
One of the stray cats here, jet black - a beauty with a gorg shiny coat - for ages he had one solitary white whisker - it was the oddest looking thing. It suddenly disappeared and it was strange not seeing his mutant follicle on his face!
