  We evaluate the three bulk viscosity coefficients $\zeta_1, \zeta_2$ and
$\zeta_3$ in the color-flavor locked (CFL) superfluid phase due to phonons and
kaons, which are the lightest modes in that system. We first show that the
computation is rather analogous to the computation of the same coefficients in
superfluid $^4$He, as due to phonons and rotons. For astrophysical
applications, we also find the value of the viscosities when there is a
periodic disturbance, and the viscosities also depend on the frequency of the
disturbance.
  In a temperature regime that might be of astrophysical relevance, we find
that the contributions of both the phonons and kaons should be considered, and
that $\zeta_2$ is much less that the same coefficient in unpaired quark matter
