  • Cats may also shed a few whiskers as they get older, but it's no reason to worry, as another one will grow back in its place. (natusan.co.uk)
  • Torsion alters the forward facing surface of the vibrissae shaft that contacts the opposing surface and, because the vibrissae are curved, displaces the whisker tips relative to the head (Knutsen et al. (scholarpedia.org)
