His original whiskers fell off - all of the 7 which he had from his first round of vincrsitine. However I am pleased to see that he is now growing others. They are fine whiskers. Grandma asled me if he would be bale to walk straight without them. I told her that he would have to adjust and I'm sure he would be able to do so. He is still able to jump up 2 ft rather well and has yet to miss his footing...even though he is now 13 years old and it seems he is a getriatric cat instead of just senior.
