Shedding Whiskers

Is it normal for a cat to shed it's Whiskers?  Petey is almost two years old and I have found over 12 whiskers on the floor.  Looking at him, it looks like he is losing them.  Is this a mineral or vitamin issue?  I'm thinking it might be normal.  Also, I've never seen Petey lose a tooth and I've had him since he was 3 months old.  Thanks for any advice you can offer me!

Yes, whiskers are modified hairs and fall out on a regular basis. They are then replaced.

Thank you for your response.  It makes sense
