So, my eldest boy cat (he's about 2) has a behavior that I find very odd: he will pin down the two younger boys (9 and 6 months) gently and start grooming their face. Then he'll select a whisker, get it between his teeth, and PULL until it comes out. It doesn't seem to bother either of the baby boys. I was wondering a few things: (1) WHY does he do this??? (2) Is it going to hurt the boys periodically growing up without whiskers (he seems to let them grow back in, then "harvest" them in about 1-2 weeks) (3) Is it going to hurt Boo (the oldest boy) to be eating so many whiskers? Thanks in advance for your opinions.
