hi, so I have a male kitty named Nugget. he is three years old, ive had him since he was 8 weeks. yesterday I found a single whisker on the ground, and then today I found two more. I’ve never had my own cat before, nor have I ever noticed him losing whiskers before. is this normal? do they shed and regrie their whiskers at certain points or something? I dunno, I just wanna make sure there’s no cause for concern
